반응 단계
A solution of m-chloroperbenzoic acid (2.16 g) in dichloromethane (40 ml) was added to a stirred solution of 5-methoxy-2-(5-methyl-6-piperidino-4-pyrimidinylmethylthio)-(1H)-benzimidazole (4.0 g) in dichloromethane (110 ml) cooled to between -40° and -50°. After a further hour at -40°, ammonia was passed through the reaction mixture and the precipitated solid filtered off. The filtrate was stripped, and the residual glass triturated with acetonitrile to give 5-methoxy-2-(5-methyl-6-piperidino-4-pyrimidinylmethylsulphinyl)-(1H)-benzimidazole 2.66 g, m.p. 87°-89°.
