実験手順
5-Chloro-7-methyl-2-mercaptobenzoxazole (200 mg) was dissolved in toluene (10 ml), N-methylhomopiperazine (1.24 ml) was added dropwise to the solution and then the mixture was stirred with heating for 1 hour. After evaporation of the solvent, the thus obtained mixture was purified by a silica gel column chromatography (methylene chloride:methanol=10:1) to obtain the title compound 5-chloro-7-methyl-2-(4-methyl-1-homopiperazinyl)benzoxazole (266 mg).
