Abstract: Veratryl cyanide is prepared by chloromethylating veratrol in solution in toluene and then reacting the resulting veratryl chloride with from 1 to 5 moles of an alkali metal cyanide, by a process in which the toluene from the chloromethylation is not removed for the reaction with cyanide, and from 3 to 25% by weight, based on veratryl chloride, of water, from 5 to 50% by weight, based on toluene, of a ketone of 3 to 6 carbon atoms and from 0.1 to 10% by weight, based on veratryl chloride, of a phase transfer catalyst are added before the reaction with cyanide.
