4-Allyloxy-3,5-dimethoxyphenethylamine · 3,5-Dimethoxy-4-allyloxyphenethylamine
SYNTHESIS: A solution of 5.8 g of homosyringonitrile (see under
A suspension of 4.0 g LAH in 150 mL anhydrous THF under N2 was cooled to 0 °C and vigorously stirred. There was added, dropwise, 2.8 mL 100% H2SO4, followed by 5.5 g 3,5-dimethoxy-4-allyloxyphenylacetonitrile in 10 mL anhydrous THF. The reaction mixture was stirred at 0 °C for a few min, then brought to a reflux on the steam bath for 30 min. After cooling back to room temperature, there was added sufficient IPA to destroy the excess hydride, followed by sufficient 10% NaOH to form granular solids. These were removed by filtration, and washed with 20 mL IPA. The filtrate and washes were stripped of solvent under vacuum andthe residue added to 100 mL dilute H2SO4. This was washed with 2×50 mL CH2Cl2, made basic with aqueous NaOH, and extracted with 2×75 mL CH2Cl2. These extracts were pooled, the solvent removed under vacuum, and the residue distilled at 110–120 °C at 0.4 mm/Hg to give 4.9 g of a colorless oil. This was dissolved in 15 mL IPA, neutralized with concentrated HCl (55 drops required), and diluted with 50 mL Et2O. The product was removed by filtration, washed with Et2O, and air dried to give 4.9 g of 3,5-dimethoxy-4-allyloxyphenethylamine hydrochloride (AL) as white crystals.
DOSAGE: 20–35 mg.
DURATION: 8–12 h.
QUALITATIVE COMMENTS: (with 24 mg) “I first became aware of something in about 10 minutes, a pleasant increase in energy. By 20 minutes it was getting pronounced and was a nice, smooth development. During the next hour positive and negative feelings developed simultaneously. Following a suggestion, I ate a bit of food even though I had not been hungry, and to my surprise all the negative feelings dropped away. I felt free to join the others wherever they were at. I moved into the creative, free-flowing kind of repertoire which I dearly love, and found everything enormously funny. Much of the laughter was so deep that I felt it working through buried depressions inside me and freeing me. From this point on, the experience was most enjoyable. The experience was characterized by clear-headedness and an abundance of energy which kept on throughout the day and evening. At one point I went out back and strolled along to find a place to worship. I had a profound sense of the Presence and great love and gratitude for the place, the people, and the activities taking place. The come-down from the experience was very gradual and smooth. Food tasted wonderful. I went to bed late, and quite ready for bed, although the energy was still running. However, sleep was not long in coming.”
(with 24 mg) “The onset was extremely gradual and graceful, with the first alert that one could really sense at about 50 minutes. This was succeeded by a slow gentle climb to the peak at one hour and fifteen minutes. The experience itself left all of the sensory modalities functional; speech was cogent and rather fluid. In fact, there was an unusual ease of free association. All throughout the session, the talk was high in spirits and somehow indicative of an inner excitement. Affect was entirely pleasant, but not exalting nor conducive to insight or to problem solving. There were no requirements for withdrawal into the self. The material seemed wholly social in nature. No visual, auditory or olfactory sharpening was in evidence. The plateau for this material seemed unusually long. I was unable to sleep for several hours, and took 25 mg Librium before sleep arrived. The next day was a lethargic and slow one, with the inner feeling that the effects had not worn off until the middle of the day following ingestion.”
(with 35 mg) “I was a distinct +1 in 35 minutes and a +2 by the end of the hour. My head congestion in no way cleared up, absolving the material from having that particular virtue. The entire experience was somewhat dissociated—I could not connect with my feelings. Although my mind remained clear, there was a hangover feeling at the end of the experiment.”
EXTENSIONS AND COMMENTARY: This compound was first explored in Prague by Leminger. He provided only the synthetic details and the statement that it was the most active compound that he had studied, with activity at 20 milligrams, with perceptual changes, color enhancement, and difficult dreams during sleep that night. Some effects persisted for more than 12 hours. Dosages above 35 milligrams remain unexplored.
As AL is one of the most potent 3,4,5-trisubstituted phenethylamines yet described, and since the corresponding amphetamines are of yet greater potency, it would be a good guess that 4-allyloxy-3,5-dimethoxyamphetamine (

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.”
The copyright for Book I of PiHKAL has been reserved in all forms and it may not be distributed. Book II of PiHKAL may be distributed for non-commercial reproduction provided that the introductory information, copyright notice, cautionary notice and ordering information remain attached.
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,
