SYNTHESIS: To a solution of 39.2 g
Under an inert atmosphere, 38 g LAH was wetted with 100 mL anhydrous Et2O, and then suspended in 1 L dry THF. This was brought up to a gentle reflux, and there was added, slowly, a solution of 43.7 g 2-nitro-1-(3,4,5-trimethoxyphenyl)propene in 160 mL THF. Refluxing was continued for 36 h, and then the reaction mixture was cooled with an external ice bath. The excess hydride was destroyed by the cautious addition of 38 mL H2O, and this was followed by 38 mL 15% NaOH, and finally another 114 mL H2O. The inorganic salts which should have ended up as a loose, granular, easily filterable mass, looked rather like library paste, but they were filtered nonetheless. Washing with THF was attempted, but it was not efficient. The combined filtrate and washes were stripped of solvent under vacuum giving 31.5 g of the crude base as an amber oil. This was dissolved in 140 mL IPA, neutralized with concentrated HCl (15 mL was required), and diluted with 650 mL anhydrous Et2O. There was an initial oily phase which on continued stirring changed to pale pink solids. These were finely ground under CH3CN to give 15.2 g of 3,4,5-trimethoxyamphetamine hydrochloride (TMA) as white crystals that melted at 195–211 °C. All aluminum salts from everywhere were dissolved in dilute HCl, and 1 kg of potassium sodium tartrate was added. There as added 25% NaOH allowed the pH to bring the pH to >9 without the precipitation of basic alumina. Extraction of this phase with CH2Cl2 was followed by removal of the solvent and salt formation as described above, allowed the isolation of an additional 6.4 g TMA. The product prepared in this manner contains some 10–15% 3,5-dimethoxy-4-hydroxyamphetamine as an impurity. A solution of 20 g of the TMA made in this manner in 200 mL 5% NaOH was extracted with 2×200 mL CH2Cl2. The pooled extracts were washed with 4×100 mL 5% NaOH, and the aqueous washes were pooled with the original base phase. The organic phase was stripped of its CH2Cl2 under vacuum to give an oil that was dissolved in 40 mL IPA, neutralized with concentrated HCl, and diluted with 400 mL anhydrous Et2O. There was the immediate formation of spectacular white crystals of pure 3,4,5-trimethoxyamphetamine hydrochloride, weighing 15.4 g and having a mp of 220–221 °C. The aqueous phase was brought to neutrality, treated with 10 g potassium dihydrogen phosphate, brought to pH 9.0 with the careful addition of NaOH, and extracted with 5×100 mL CH2Cl2. Evaporation of the solvent under vacuum gave an oil that spontaneously crystallized. This product, 3,5-dimethoxy-4-hydroxyamphetamine could be further purified by sublimation at 130 °C at 0.2 mm/Hg. It was a white crystalline solid that slowly discolored in the air. The literature describes a picrate salt with a mp of 225 °C from EtOH.
DOSAGE: 100–250 mg.
DURATION: 6–8 h.
QUALITATIVE COMMENTS: (with 135 mg) “I had no nausea, although I always vomit with
(with 140 mg) “There were not the color changes of
(with 225 mg) “There was quite a bit of nausea in the first hour. Then I found myself becoming emotionally quite volatile, sometimes gentle and peaceful, sometimes irritable and pugnacious. It was a day to be connected in one way or another with music. I was reading Bernstein’s ‘Joy of Music’ and every phrase was audible to me. On the radio, Rachmaninoff’s 2nd piano concerto on the radio put me in an eyes-closed foetal position and I was totally involved with the structure of the music. I was suspended, inverted, held by fine filigreed strands of the music which had been woven from the arpeggios and knotted with the chords. The commercials that followed were irritating, and the next piece, Slaughter on Fifth Avenue, made me quite violent. I was told that I had a, ‘Don’t cross me if you know what is good for you,’ look to me. I easily crushed a rose, although it had been a thing of beauty.”
EXTENSIONS AND COMMENTARY: TMA was the very first totally synthetic psychedelic phenethylamine that was found to be active in man, for which there had been any attempt to describe such drug effects in any detail. This was the report of research done in Canada, and it appeared in 1955, six years before my own report on the material. There was an earlier report on
The Canadian studies with TMA involved the use of a stroboscope as a tool for the induction of visual phenomena. These experiments used levels in the 50–150 milligram range, and generally employed pre-treatment with Dramamine for the successful prevention of nausea. There was reported giddiness and light-headedness, and some remarkable flash-induced visualizations. With higher levels, the visual syntheses are present without external stimulation. But there is a thread of negativity that seems to pervade the experience at these higher levels, and the appearance of a publication that emphasized the possible antisocial nature to TMA seemed to discourage further medical exploration. Military interest was maintained however, apparently, as TMA became a part of the chemical warfare studies where it was referred to with the code name EA-1319. It had been used in human trials with psychiatric patients, but no details of these experiments have been published.
The presence of a potentially active impurity in TMA deserves some comment. In the Canadian work, the material used was described as melting at 219–220 °C, which is the property given for the impurity-free material above. If this was the actual material used in those studies, this impurity (3,5-dimethoxy-4-hydroxyamphetamine) was probably not present. The Army studies use a material of unreported melting point. In my own studies, the lower melting product was used. There is an intriguing and unanswered question: what contribution did this phenolic component make to the nature of the observed effects of TMA? Assays on the isolated contaminant could answer that, but they have not yet been made.
There is an old saying that has gotten many people into trouble: “If one is good, then two is better.” And if a statement of the measure of worth of a compound can be made from its potency, then TMA is a step in the right direction. And this was a chemically simple direction to follow further. Looking at
Using this pattern of naming, TMA can be seen as α-methylmescaline, or AMM. And the two carbon homologue would be α-ethylmescaline, or
A final comment. But maybe a long one! Elsewhere, I have made comparisons between essential oils and the amphetamines? In a word, there are some ten essential oils that have a three carbon chain, and each lacks only a molecule of ammonia to become an amphetamine. So, maybe these essential oils, or “almost” amphetamines, can serve as an index for the corresponding real amphetamine counterparts. I had originally called this family the “natural” amphetamines, but my son suggested calling them the “essential” amphetamines, and I like that. At the time that I had synthesized TMA, back there in the ’50s, I had the impulse to explore this body of essential amphetamines. As the old folk-wisdom says: “Nature is trying to tell us something.”
One of the banes of the archivist is having to choose one pattern of organization over another. The book store owned by a language scholar will have the German poets and playwrights and novelists here, and the French ones over there. Next door, the book store is run by a letters scholar, and the poetry of the world is here, and the plays of the world are there, regardless of the language of origin. The same obtains with spices, and essential oils, and amphetamines. The spice cabinet is a rich source of chemical treasures, each source plant containing a host of compounds, some of which are true essential oils. And the next spice from the next plant has some of the same components and some new ones. Does one organize by plant (spice or herb) or by essential oil (amphetamine)? Let’s do it by the ring substitution pattern of the amphetamine, and gather the spices and oils as a secondary collection.
(1) The 4-methoxy pattern. The pivotal essential oil is 4-allylanisole, or methyl chavicol, or
(2) The 3,4-dimethoxy pattern. The main actor here is essential oil analysis.
The compounds missing that methyl group on the 4-oxygen are famous. The allyl material is
The isomer with the other methyl group missing is
The 2,4-isomer is called
And the 3,5-dimethoxyallylbenzene isomer from artemisia (a pungent herb commonly called mugwort) and from sage, would give rise to
(3) The 3,4-methylenedioxy pattern. One of the most famous essential oils is
(4) The 3-methoxy-4,5-methylenedioxy pattern. The parent compound is Myristica fragrans and mace is the fibrous covering of the seed. The two spices are virtually identical as to their chemical composition. essential oils and the essential amphetamines. Care must be taken to make an exact distinction between essential oil) and myristin (the fat) which is really trimyristin or glyceryl trimyristate from nutmeg and coconut. This is the fat from myristic acid, the C-14 fatty acid, and these two similar names are often interchanged even in the scientific literature.
(5) The 2-methoxy-3,4-methylenedioxy pattern. This is the second of the three natural methoxy methylenedioxy orientations. Eriostemon crowei from the worlds of rue and the citrus plants. It corresponds to the essential amphetamine Ruta graveolens, the common rue, whose small leaves smelled to me, for all the world, like cat urine. This plant has always fascinated me because of a most remarkable recipe that I was given by a very, very conservative fellow-club member, one evening, after rehearsal. He told me of a formula that had provided him with the most complete relief from arthritic pain he had ever known. It was a native decoction he had learned of many years eariler, when he was traveling in Mexico. One took equal quantities of three plants, Ruta graveolens (or our common rue), Rosmarinus officinalis (better known as rosemary), and Cannabis sativa (which is recognized in many households simply as marijuana). Three plants all known in folklore, rue as a symbol for repentance, rosemary as a symbol of remembrance, and pot, well, I guess it is a symbol of a lot of things to a lot of people. Anyway, equal quantities of these three plants are allowed to soak in a large quantity of rubbing alcohol for a few weeks. Then the alcoholic extracts are clarified, and allowed to evaporate in the open air to a thick sludge. This then was rubbed on the skin, where the arthritis was troublesome, and always rubbed in the direction of the extremity. It was not into, but onto the body that it was applied. All this from a very conservative Republican friend!
The methoxy-methylenedioxy pattern is also found in nature with the 2,4,5-orientation pattern. The allyl-2,4,5-isomer is called
(6) The 3,4,5-trimethoxy pattern. essential oil, 5-allyl-1,2,3-trimethoxybenzene, primarily from the oil of elemi. It is, like
I had found a trace component in nutmeg many years ago that proved to be
(7) The 2,4,5-trimethoxy pattern. There is an essential oil called Acorus calamus, the common Sweet Flag that grows wild on the edges of swamps throughout North America, Europe, and Asia. It has been used as a flavoring of liqueurs and, as almost every other plant known to man, has been used as a medicine. In fact, in Manitoba this plant was called Rat-root by the Cree Indians in the Lake Winnipeg area known as New Iceland, and Indian-root by the Icelandic pioneers. It was used externally for the treatment of wounds, and internally for most illnesses. There apparently is no report of central effects. The corresponding propanone, Asiasarum which looks very much like the name asarone, which comes from the Genus Acorus. And a second Genus of medical plants also called wild ginger is simply called Asarum. There is an Asarum forbesi from central China, and it is known to give a pleasant smell to the body. And there is Asarum seiboldi which is largely from Korea and Manchuria. It has many medical uses, including the treatment of deafness, epilepsy, and rheumatism. The amphetamine that would arise from this natural treasure chest is
(8) The 2,5-dimethoxy-3,4-methylenedioxy pattern. The parent allyl benzene is essential oils are white solids, there is a green oily liquid that had been broadly used years ago in medicine, called green, or liquid apiol (without the final “e”). It comes from the seeds of parsley by ether extraction, and when the chlorophyll has been removed, it is known as yellow apiol. With the fats removed by saponification and distillation, the old term for the medicine was apiolin. I would assume that any of these would give rise to white, crystalline
(9) The 2,3-dimethoxy-4,5-methylenedioxy pattern. The second of the three tetraoxygenated essential oils is 1-allyl-2,3-dimethoxy-4,5-methylenedioxybenzene, commonly called
(10) The tetramethoxy pattern. The third and last of the tetra-oxygenated essential oils, is essential amphetamines,
One must remember that the term “essential” has nothing to do with the meaning of needed, or required. The word’s origin is essence, something with an odor or smell. Thus, the essential oils are those oils that have a fragrance, and the essential amphetamines are those compounds that can, in principle, be made from them by the addition of ammonia in the body.
There were a few interesting experimental trials that were based on these natural oils. Methoxyeugenol was assayed up to a 10 milligram level, and asarone at up to a 70 milligram level, and neither had any effects at all. And, in an attempt to challenge the “oil-to-amphetamine” concept, I made up a mixture of 1 part

About PiHKAL · info
This version of Book II of PiHKAL is based on the Erowid online version, originally transcribed by Simson Garfinkle and converted into HTML by Lamont Granquist. I drew also on “Tyrone Slothrop’s” (Unfinished) Review of PIHKAL to enumerate the many analogues mentioned in PiHKAL but not described at length. Many, many others have since been added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”
