Resumen:
7-Substituted 3,7-dihydro-4H-pyrazolo[3,4-d][1,2,3]triazin-4-ones 2a-d were conveniently prepared by direct diazotization of 5-aminopyrazole-4-carbonitriles 1a-d in HCl media. Different reaction conditions and the effects of substituents on N-1 of the pyrazole ring were studied. A possible mechanistic exlpanation of the observed process is proposed.
