Procedure

The title compound was prepared by the method of Example 1 using 4.36 g of 2-mercapto-5-(trifluoromethyl)benzimidazole instead of 2-mercaptobenzimidazole and 3.56 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 2.40 g of the title compound: m.p. ca. 155° C. Analysis. Calc'd. for C15H12N3F3S: C, 55.72; H, 3.74; N, 13.00; S, 9.92; F, 17.63. Found: C, 55.55; H, 3.68; N, 13.10; S, 10.12; F, 17.38.
