The reaction of 1-aryl-4-ethoxycarbonyl-5-amino-1,2,3-triazole (1) with formamide, isocyanic acid sulfonyl chloride and imide ethers was studied. (2a-c), 5-N-methyl-1-aryl-1,2,3,4-triazolo [4,5-e] 4,5-e] pyrimidin-4-one (3a-c), 1-aryl-4-ethoxycarbonyl-5-ureido-1,2,3-triazole (5a, b), 5-H-1-aryl-1,2,3-triazolo [4,5-e] pyrimidine- Phenyl-1,2,3-triazolo [4,5-e] piperidine [1,2-b] pyrimidin-4-one (6a) Their structures were confirmed by elemental analysis, IR, NMR, and mass spectrometry. The results showed that The special representative of biological activity.
