SYNTHESIS: To a well stirred solution of 25 g ethanolamine hydrochloride in 75 mL MeOH there was added 4.45 g of 3,4-methylenedioxyphenylacetone (see under MDMA for its preparation) followed by 1.1 g sodium cyanoborohydride. Concentrated HCl in MeOH was added as required, over the next few days, to maintain the pH at about 6 as determined with external, dampened universal pH paper. The reaction mixture was added to 300 mL H2O and made strongly acidic with an excess of HCl. After washing with 3×100 mL CH2Cl2 the aqueous phase was made basic with 25% NaOH, and extracted with 4×100 mL CH2Cl2. Removal of the solvent under vacuum yielded 3.5 g of a viscous off-white oil that was distilled at 160 °C at 1.3 mm/Hg to give 2.0 g of a white viscous oil. The pot residue remained fluid, but was discarded. This distillate was dissolved in 8.0 mL IPA to give, eventually, a clear solution. This was neutralized with concentrated HCl and diluted with 100 mL anhydrous Et2O. The loose white crystals of 3,4-methylenedioxy-N-(2-hydroxyethyl)amphetamine hydrochloride (MDHOET) that formed were removed by filtration, washed with Et2O, and air dried. These weighed 2.3 g, and had a mp of 147–148 °C. Anal. (C12H18ClNO3) N.
DOSAGE: greater than 50 mg.
EXTENSIONS AND COMMENTARY: Most compounds with bare, exposed polar groups like hydroxyls are not centrally active, as they simply do not have any way of getting into the brain. MDHOET is certainly not very active, if it is active at all.
There was one report that at very high doses some central effects were indeed observed. With quantities in the several hundreds of milligrams a picture emerged of changes in perceived color and depth perception, but without euphoria. It was said to resemble a mild dose of ketamine. This is an interesting comment, in that ketamine has found its major medical use as an anesthetic, and MDHOET is among the most effective of all the N-substituted MDA derivatives assayed in several animal analgesia models.
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. Still others remain to be added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore most of the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice, and in the hope of aligning with more readers’ searches. Typically the change is little more than expanding a prefix and setting it in italics. The errata and changes 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.
Although 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,
