Resumo

The reactivity of ethyl 7-azido-3-tert-butyl-4-oxo-4,6-dihydropyrazolo[5,1-c][1,2,4]triazine- 8-carboxylate was studied and new 4-oxo-7-(1H-1,2,3-triazol-1-yl)-4,6-dihydropyrazolo- [5,1-c][1,2,4]triazines were synthesized. The stability of the pyrazolo[5,1-c][1,2,4]triazine system to Cr^VI oxidants was considered, the reaction course and conditions were studied. Spectral characteristics of products are discussed.
