A noveland practical synthesis of substituted 2-ethoxy benzimidazole: Candesartan cilexetil

A novel and practical synthetic route for the preparation of candesartan cilexetil from methyl 2-amino-3-nitrobenzoate is described.The key steps are the reaction of methyl 2-bromo-3-(diethoxy-methyleneamino)benzoate with (2-(1-trityl-1H-tetrazol-5-yl) biphenyl-4-yl) methanamine and the final formation of 2-ethoxy benzimidazole ring via intramolecular N-arylation.The final ring closure process could be utilized to prepare other 2-substituted benzimidazoles.The method is simple for operation and suitable for industrial production.
