A straightforward and metal-free synthesis of N-1-alkyl-2-unsubstituted benzimidazoles from the corresponding o-fluoro aryl formamidines and primary amines using microwave irradiation is described. The displacement of -F by the primary amine and cyclization to form the corresponding benzimidazoles took place in one pot.
