Abstract
Reaction of 6-nitroazolo[1,5-a]pyrimidines with cyanoacetamide, cyanoacetthioamide, or benzoylacetonitrile results in the conversion of the pyrimidine ring into a pyridine ring with the formation of 2-azolylamino-5-nitropyridines. Treatment of the latter with alcoholic sodium carbonate, or reaction of the azolopyrimidines with acetonitriles in an alkaline medium, affords 7-nitroazolo]1,5-a]pyrido[2,3-d]pyrimidines.
