The title compound was prepared by the method of Example 1 using 2.50 g of 2-mercapto-5-methylbenzimidazole instead of 2-mercaptobenzimidazole and 2.71 g of 2-(chloromethyl)aniline hydrochloride instead of 2-(chloromethyl)-N,N-dimethylaniline in isopropyl alcohol. The basic extraction used 5% sodium hydroxide instead of sodium carbonate. Washing the solid residue from the dichloromethane extract with additional dichloromethane gave 1.65 g of the title compound. Analysis. Calc'd. for C15H15N3S: C, 66.89; H, 5.61; N, 15.60; S, 11.90. Found: C, 65.78; H, 5.48; N, 15.54; S, 11.94.
