It was shown that hetarylation of benzimidazol-2-ylacetonitriles by 2,3-dichloroquinoxaline proceeds at the methylene group.The reaction of 2-chloro-3-<α-cyano-α-(benzimidazol-2-yl)methylene>-3,4-dihydroquinoxalines formed with primary amines leads to 1-R-2-amino-3-(benzimidazol-2-yl)pyrrolo<2,3-b>quinoxalines.
