Abstract

PURPOSE: To prepare the titled compound useful as a raw material of cationic dyes and an intermediate of photographic chemicals, under mild conditions, in high yield, by reacting aniline with chloro-methylbutanone under specific conditions, cooling the reaction products, and washing the filtrate with an acid.
CONSTITUTION: 1mol of 3-chloro-3-methylbutan-2-one is mixed with 2W10mol of aniline, and made to react at 0W100°C, pref. 20W70°C, for 1W10 days. After the reaction, the system is allowed to cool to ≤30°C, and crystallized aniline hydrochloride is separated by filtration. The filtrate is mixed with pref. a hydrocarbon solvent, precipitated insoluble matter is separated, and the solution is washed with an aqueous solution of an acid and with water, dried, subjected to the solvent removal, and distilled under vacuum to obtain the objective compound.
