- Abstract
The article discusses the synthesis of the heterocyclic system 9-methyl-8-phenyl-1,4-dihydro-5h-pyrazolo-[5',1':2,3]pyrimido[4,5-e][1,2,4]triazepin-5-one. The reaction of ethyl 7-imino-2-methyl-3-phenyl-4,7-dihydropyrazolo[1,5-a]pyrimidine-6-carboxylate with hydrazine hydrate produced the compound 7-imino-2-methyl-3-phenyl-4,7-dihydropyrazolo-[1,5-a]pyrimidine-6-carbohydrazide. Hydrogen nuclear magnetic resonance (HNMR) confirmed the formation of the pyrazolopyrimidotriazepino system.
