Abstract

A process of synthesizing 2-bromo-LSD or a salt or hydrate thereof comprising the steps of reacting methylergometrine with a brominating agent to produce [(1S)-1-(Hydroxymethyl)propylamino][(6aR,9R)-5-bromo-7-methyl-4,7-diaza-4,6,6a,7,8,9-hexahydroacephenanthrylen-9-yl]formaldehyde as a first intermediate, and then hydrolyzing [(1S)-1-(Hydroxymethyl)propylamino][(6aR,9R)-5-bromo-7-methyl-4,7-diaza-4,6,6a,7,8,9-hexahydroacephenanthrylen-9-yl]formaldehyde to yield bromo-lysergic acid as a second intermediate, wherein bromo-lysergic acid is then amidated to yield 2-bromo-LSD or a salt or hydrate thereof.

Claims (1)

1. A process of synthesizing 2-bromo-LSD or a salt or hydrate thereof comprising the step of reacting bromo-lysergic acid with POCl 3 , wherein a ratio of an amount of POCl 3 to an amount of bromo-lysergic acid ranges from about 1:1 to about 1:3.
