1-Dimethylaminomethyl-LSD is a lysergamide derivative related to the psychedelic drug lysergic acid diethylamide (LSD). [1] [2] [3] [4] [5] It was synthesized and described by Albert Hofmann and Franz Troxler at Sandoz in 1957. [1] [3] [4] [5] According to Alexander Shulgin in his 1997 book TiHKAL (Tryptamines I Have Known and Loved), 1-dimethylaminomethyl-LSD has been limitedly described, and it is unknown whether it was ever tested in humans. [1] The 2-dimethylaminomethyl-LSD positional isomer has also been described, and was found to have 18.5% of the antiserotonergic activity of LSD in vitro . [6]
The hydrogen atom in position 1 of LSD was substituted by the following radicals: acetyl, methyl, hydroxymethyl and dimethylaminomethyl (24,25). [...] 1-Dimethylaminomethyl-d-lysergic acid diethylamide was formed by Mannich-reaction, when a solution of LSD (free base) in glacial acetic acid was added with diethylamine followed by formaldehyde. [...] 1-Dimethylaminomethyl-LSD is resistant to hydrolysis in diluted alkaline or acid solutions at room temperature, but is hydrolyzed when these solutions are heated.

Table II summarizes the substitutions which have been made in the ring system of LSD (TROXLER and HOFMANN, 1957). [...] TABLE II: Substitutions in the ring system: [...] R1 = CH2N(CH3)2. R2 = H. Dimethylaminomethyl-LSD
Reaction of formaldehyde with lysergic acid esters or amides easily yielded the corresponding I-hydroxymethyl derivatives of general formula (36c). It was, therefore, no surprise that a reaction of the Mannich type with formaldehyde and dimethylamine led to I-dimethylaminomethyl lysergic acid derivatives, (36d). Michael addition of acrylonitrile gave rise to I-cyanoethyl derivatives, formula (36e). All these compounds proved to be moderately stable against acids and bases. (TROXLER and HOFMANN, 1957b).
