The NaH-mediated N-methylbenzimidazole formation starting from carbonitriles and N-methyl-1,2-phenylenediamine is reported to be a procedure compatible with acid-labile acetal protective groups within the starting materials. Products were further converted in Suzuki, Sonogashira, Heck and Buchwald-Hartwig reactions.
