Procedure
A mixture of 2-chloro-4-(4-chlorophenyl)-5-[3-(2-methoxyphenoxy)propyl]oxazole (378 mg), N-methylethanolamine (750 mg) and 2-butanone (10 ml) was stirred with heating under reflux for 6 hours. The reaction mixture was poured into water (100 ml) and extracted with ethyl acetate (100 ml×2). The organic layer was washed with water (100 ml), dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography, and 4-(4-chlorophenyl)-2-[N-(2-hydroxyethyl)-N-methylamino]-5-[3-(2-methoxyphenoxy)propyl]oxazole was obtained as an oil (108 mg, 26%) from an ethyl acetate-hexane (1:1, v/v)-eluted fraction.
