HETEROARYLATION OF ACETONITRILES. 3. HETREOARYLATION OF PYRIDIN-2-YL AND QUINOLIN-2-YLACETONITRILES BY CHLOROQUINOXALINES
It has been shown that α-chloroquinoxalines heteroarylate pyridin-2-yl and quinolin-2-ylacetonitriles primarily at the methylene group.A method has been developed for synthesizing 1-R-2-amino-3-heteroarylpyrroloquinoxalines permitting the preparation of compounds containing the pyridine and quinoline nuclei.

(HET)ARYLATION OF SUBSTITUTED ACETONITRILES. 1. SYNTHESIS OF 2-AMINO-3-(BENZIMIDAZOL-2-YL)PYRROLOQUINOXALINES
It was shown that hetarylation of benzimidazol-2-ylacetonitriles by 2,3-dichloroquinoxaline proceeds at the methylene group.The reaction of 2-chloro-3--3,4-dihydroquinoxalines formed with primary amines leads to 1-R-2-amino-3-(benzimidazol-2-yl)pyrroloquinoxalines.
