Reaction of ethyl 5‐amino‐1‐phenyl‐1H‐pyrazole‐4‐carboxylate with thiocarbohydrazide yielded 5‐amino‐6‐hydrazinyl‐1‐phenyl‐1H‐pyrazolo[3,4‐d]pyrimidine‐4‐(5H)one (1), which used as precursor to synthesize pyrazolopyrimidotriazepine 2, pyrazolopyrimidotriazines 5‐7, pyrazolotriazolopyrimidines 8‐14, pyrazolopyrimidotetrazines 17. The structures of the newly synthesized compounds were confirmed by spectral data (IR, NMR, elemental analysis, and mass spectra).
