for the N-methylthiomethylation of benzimidazoles has been developed employing DMSO as a solvent and as a reagent. This methodology has been applied for the synthesis of diverse N-methylthiomethyl derivatives of benzimidazoles. The products can be chemoselectively oxidized to the corresponding sulfoxides with NaBiO3 in acetic acid. Both the N-methylthiomethyl derivatives of benzimidazoles and their
