Procedure

The title compound was prepared by the method of Example 1 using 1.68 g (9.33 mmole) of 2-mercapto-5-methoxybenzimidazole instead of 2-mercaptobenzimidazole and 1.99 g (11.2 mmole) of 2-(chloromethyl)aniline hydrochloride instead of 2-(chloromethyl)-N,N-dimethylaniline in 250 ml of isopropyl alcohol. The basic extraction used 5% sodium hydroxide instead of sodium carbonate. Chromatography on silica gel, followed by crystallization from diethylether, gave 520 mg of pure title compound: m.p. 140-142° C. Analysis. Calc'd. for C15H15N3OS: C, 63.14; H, 5.30; N,14.73; S, 11.23. Found: C, 63.44; H, 5.42; N, 14.43; S, 11.07.
