SYNTHESIS: A solution of 50 g myristicinaldehyde (3-methoxy-4,5-methylenedioxybenzaldehyde, see under 2O and cooled in an external ice-acetone bath. A heavy crop of yellow crystals formed, which were removed by filtration, washed with cold acetic acid, and dried to constant weight. There was thus obtained 19.3 g 3-methoxy-4,5-methylenedioxy-β-nitrostyrene with a mp of 210–212 °C. The mother liquors were diluted with H2O, and extracted with 3×100 mL CH2Cl2. The pooled extracts were washed with 5% NaOH, and the solvent removed under vacuum yielding 34 g of a dark residue that was largely unreacted aldehyde. This residue was reprocessed in acetic acid with nitromethane and ammonium acetate, as described above, and provided an additional 8.1 g of the nitrostyrene with the same mp.
A suspension of 25 g LAH in 1.5 L anhydrous Et2O in an inert atmosphere was stirred magnetically, and brought up to a gentle reflux. Through a Soxhlet condenser modified to allow Et2O to return continuously to the reaction mixture, there was added 27.0 g of 3-methoxy-4,5-methylenedioxy-β-nitrostyrene. The addition require many h, and when it was completed, the reaction was held at reflux for an additional 9 days. After cooling the reaction mixture in an external ice bath, the excess hydride was destroyed by the cautious addition of dilute H2SO4. The final amount used was 1800 mL H2O containing 133 g H2SO4. The phases were separated, and the aqueous phase was washed with 2×100 mL Et2O. To it was then added 625 g potassium sodium tartrate, and sufficient base to bring the pH to >9. This was extracted with 3×250 mL CH2Cl2, and the pooled extracts stripped of solvent under vacuum. The residue was dissolved in anhydrous Et2O and saturated with anhydrous HCl gas, giving a heavy crystallization of salts. These were removed by filtration, Et2O washed, and air dried, to give 17.7 g 3-methoxy-4,5-methylenedioxyphenethylamine (LOPHOPHINE) as an off-white solid with a mp of 160–161 °C. This was dissolved in CH3CN containing 5% EtOH, decolorized with activated charcoal, filtered, and the removed charcoal washed with boiling CH3CN. Slow cooling of the solution provided 11.7 g of a white product which melted at 164–164.5 °C.
DOSAGE: greater than 200 mg.
QUALITATIVE COMMENTS: (with 150 mg) “Between two and five hours, very peaceful and euphoric mood elevation, similar to
(with 250 mg) “Possibly something of a threshold effect from 2:30 to 4:30 of the experiment. Intangible, and certainly there is nothing an hour later.”
EXTENSIONS AND COMMENTARY: It looks as if this compound is not active. There is an excellent argument as to why it really should be, and the fact that it is not active is completely unexpected. Let me try to explain.
It is inevitable that this simple and most appealing precursor will be found to be present in the cactus, at some future time when we will have tools of sufficient sensitivity to detect it. And certainly, it would be reasonable to expect it to be an active psychedelic, and to be as interesting in man as its close cousin,
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.
