DMT (desoxymethyltestosterone) synthesis:
React epiandrosterone with p-toluenesulfonyl chloride and trimethylpyridine to remove the hydroxyl group at C-3 of the steroid ring system. A pair of olefin isomers form, the 3-ene and 2-ene. Reaction of these intermediates with methyllithium adds a methyl group to C-17 and converts the keto group there to a hydroxyl group, resulting in DMT.
