5,7-Dimethyl-2-mercaptobenzoxazole (220 mg) was dissolved in chloroform (20 ml), N-methylhomopiperazine (0.76 ml) was added dropwise to the solution and then the mixture was stirred with heating for 2 days. After evaporation of the solvent, the thus obtained mixture was purified by a silica gel column chromatography (methylene chloride:methanol=20:1) to obtain the title compound 5,7-dimethyl-2-(4-methyl-1-homopiperazinyl)benzoxazole (110 mg).
