Procedure
5-Methyl-2-mercaptobenzoxazole (200 mg) was dissolved in chloroform (20 ml), N-methylhomopiperazine (1.24 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=10:1) to obtain the title compound 5-methyl-2-(4-methyl-1-homopiperazinyl) benzoxazole (124 mg).
