Reaction Steps

A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methoxyphenoxy)propyl]oxazole (378 mg), an aqueous solution of dimethylamine (50%, 1.0 ml) and 2-butanone (10 ml) was stirred with heating under reflux for 12 hours. The reaction mixture was concentrated, the residue obtained was subjected to silica gel column chromatography, and 4-(4-chlorophenyl)-2-dimethylamino-5-[3-(2-methoxyphenoxy)propyl]oxazole was obtained as an oil (348 mg, 90%) from an ethyl acetate-hexane (1:4, v/v)-eluted fraction. Crystallization from acetone-hexane gave pale yellow prisms. Melting point 67-68° C.
