The present invention is a process for the introduction of a nucleophilic group into a benzimidazole or imidazo[4,5-b or c]pyridine ring, which comprises treating a derivative of the corresponding 1-hydroxybenzimidazole or -imidazo[4,5-b or c]pyridine with a nucleophilic reagent. The process can also be used to reduce the 1-hydroxybenzimidazole or -imidazo[4,5-b or c]pyridine.
