Abstract Effect of the molar ratio between reagents, temperature, and synthesis duration on the yield of 3-pyridylsubstituted 5-amino-1, 2, 4-triazoles in the reaction of aminoguanidine hydrochloride with pyridinecarboxylic acids under acid catalysis conditions was studied. A single-reactor method for synthesis of 3-pyridyl-substituted 5-amino-1, 2, 4-triazoles and their hydrochlorides was developed.
