Procedure
Analogous reaction of 2,2-difluoro-5H-[1,3]-dioxolo[4,5-f]benzimidazole-6-thiol with 2-chloromethyl-4-methoxy-3,5-dimethylpyridine gives 2,2-difluoro-6-[(4-methoxy-3,5-dimethyl-2-pyridyl)methylthio]-5H-[1,3]-dioxolo[4,5-f]benzimidazole, of m.p. 148°-149° C. (from acetonitrile), in 86% yield.
