A novel and efficient approach to the synthesis of 2‐substituted benzimidazoles has been developed via CuI/DMEDA‐catalyzed coupling reaction and post‐cyclization with glacial acetic acid from readily available 2‐iodoanilines and amides. This method is suitable for the construction of a variety of benzimidazoles in moderate to good yields under short reaction times.
