Upon interaction with caustic in a DMSO medium, 2-chloromethylbenzimidazoles are subjected to cyclodimerization, forming 5H,12H-pyrazinobis-benzimidazoles; in the presence of nucleophiles (ammonia, amines, anions of β-diketones), under the indicated conditions, the products are the corresponding substituted amines or derivatives of pyrrolobenzimidazole.
