5,7-Dimethyl-2-mercapto-benzoxazole (109 mg) was dissolved in toluene (6 ml), and the solution was mixed with 1,4-diazacyclooctane (1.93 g) which has been obtained in accordance with the method described in Carib. J. Sci., 14, 77 (1974) and then stirred with heating for 3 hours. After evaporation of the solvent, the thus obtained mixture was purified by a silica gel column chromatography (methylene chloride:methanol=5:1) to obtain the title compound 5,7-dimethyl-2-(1,4-diazacyclooctanyl)benzoxazole (271 mg).
