Tertiary amines containingtertiaryalkyl or aryl groups were synthesized by the reaction of a ketone with an amine and 1,2,3-triazole followed by substitution of the triazole adduct with a Grignard reagent. Thus, 1,2,3-triazole serves as a safer and practical alternative to cyanide in the Bruylants reaction.

The preparation of important pharmaceutically active highly branched tertiary amines by the reaction of Grignard reagents with adducts of cyclic ketones, benzotriazole (or pyrazole) and secondary amines is far superior to previously available routes.
