Studies with Polyfunctionally Substituted Heteroaromatics: A Route for the Synthesis of Substituted [1,2,4]Triazolo[1,5-a]pyridines

N-Arylmethylidene-2-cyanoacetohydrazides react with arylmethylidenemalonitriles to afford [1,2,4]triazolo[1,5-a]pyridinones, and with both malononitrile and ethyl cyanoacetate to afford N-aminopyridinones.
