SYNTHESIS: To a solution of 100 g of 2,3-dihydroxyanisole in 1 L dry acetone there was added 110 g of powdered anhydrous K2CO3 followed by 210 g of methylene iodide. This was brought up to a reflux on the steam bath. There was a sudden appearance of a solid phase, and then a gentle reflux was maintained for three days, during which time much of the heavy solid that initially formed had redissolved. The reaction mixture was filtered to remove the insoluble salts, and these were washed with hot acetone. The combined mother liquor and washes were stripped of solvent under vacuum, leaving a solid residue. This was leached with several portions of boiling hexane. These were pooled, and removal of the solvent under vacuum provided 53.6 g of 2,3-methylenedioxyanisole as white crystals with a sharp spicy smell.
A mixture of 120 g N-methylformanilide and 137 g POCl3 was allowed to incubate at ambient temperature for 0.5 h, then there was added 53 g of crude 2,3-methylenedioxyanisole. The dark reaction mixture was heated on the steam bath for 2 h and then poured into a beaker filled with shaved ice. This was stirred until hydrolysis was complete, and the black, almost crystalline gunk that separated was removed by filtration. The 53.6 g of crude product was analyzed by GC using an ethylene glycol succinate column at 190 °C. Three peaks were apparent and had baseline separation. The major peak at 7.8 min constituted 82% of the product and was
To a solution of 3.5 g 2-methoxy-3,4-methylenedioxybenzaldehyde in 14 g acetic acid there was added 1.4 g anhydrous ammonium acetate and 2.3 mL of nitroethane. The mixture was brought to reflux and held there for 35 min. It was then quenched by the addition of 40 mL H2O, knocking out an orange, gummy solid. This was removed by filtration, and recrystallized from 50 mL boiling MeOH. After cooling for a few h in an ice bath, the bright yellow crystals were removed by filtration, washed with MeOH and air dried to constant weight, yielding 2.15 g 1-(2-methoxy-3,4-methylenedioxyphenyl)-2-nitropropene. The mp was 106–107 °C. Recrystallization from EtOH raised this mp to 109.5–110.5 °C.
A suspension of 2.2 g LAH in 300 mL anhydrous Et2O under an inert atmosphere was brought to a gentle reflux. The reflux condensate was passed through a modified Soxhlet thimble containing 1.95 g 1-(2-methoxy-3,4-methylenedioxyphenyl)-2-nitropropene effectively adding it, over the course of 0.5 h, to the reaction mixture as a saturated Et2O solution. The mixture was maintained at reflux for 16 h. After cooling to 0 °C with an ice bath, the excess hydride was destroyed by the addition of 1.5 N H2SO4. The phases were separated, and the aqueous phase washed with 2×100 mL Et2O. To the aqueous phase there was added 50 g potassium sodium tartrate followed by sufficient 25% NaOH to raise the pH >9. This was then extracted with 3×100 mL CH2Cl2, and the solvent from the pooled extracts removed under vavuum. The residual white oil was dissolved in 250 mL anhydrous Et2O, and saturated with anhydrous HCl gas. There was produced a crop of white microcrystals of 2-methoxy-3,4-methylenedioxyamphetamine hydrochloride (MMDA-3a) which was removed by filtration, washed with Et2O, and air dried to a constant weight of 1.2 g. The mp was 154–155 °C.
DOSAGE: 20–80 mg.
DURATION: 10–16 h.
QUALITATIVE COMMENTS: (with 20 mg) “I became aware at about an hour, and an hour later I found myself suddenly caught up in the marvelous world of insects. Right alongside a pile of bricks I saw a measuring worm, and with great tenderness and patience I picked him up, observed his fore and aft ‘feet’ and finally replaced him and watched him acclimate himself. There was also a spider on the bricks, and I was compelled to watch him in action. I was grateful that I was not being observed. Time was moving slowly, and I felt I should intentionally move slowly, so as not to exhaust myself.”
(with 40 mg) “This developed between one and two hours into it, and there were considerable body tremors. Talking directed the energy outwards, and I became aware of a visually sparkling world about me. I started dropping way too soon; it would have been interesting to have gone higher. By early evening I was left only with an awareness of some residual physical hypersensitivity, and there was light diarrhea. I am not at all sure just what to compare this drug to. It is gentle.”
(with 60 mg) “There were visuals of a soft sort—things moved with eyes open, and with eyes closed the music was great. There seemed to be some lasting stimulation, but it didn’t get in the way of sleeping. The next morning, however, I was still on. A good compound.”
EXTENSIONS AND COMMENTARY: The term MMDA-3a has the feel of being complicated, but there is a reason for the code. As had been mentioned, essential oil
I have been told of a number of clinical trials that have explored MMDA-3a at considerably higher levels, but I have no explicit quotations to give, and the details are quite sketchy. Three trials at 80 milligrams, and one at 100 milligrams, all made comparisons, in both quantity and quality of the experience, to 100 micrograms of
And, as with
The 4-carbon analog was made similarly (from the aldehyde and nitropropane but using tert-butylammonium acetate as a reagent in 100% excess and isopropanol as solvent, giving bright yellow crystals melting at 105.5–106.5 °C from 25 volumes of boiling methanol) followed by reduction (with lithium aluminum hydride in ether) to give 1-(2-methoxy-3,4-methylenedioxyphenyl)-2-aminobutane hydrochloride (

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.”

PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of phenethylamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of PiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
PiHKAL (ISBN 0-9630096-0-5) is available for US$24.50 (plus $10 domestic first-class shipping) from Transform Press.Transform Press,
