Synthesis, antitumor, cytotoxic and antioxidant evaluation of some new pyrazolotriazines attached to antipyrine moiety

Iminopropanehydrazonoyl cyanide 4 was achieved upon reaction of antipyrine diazonium salt 2 with 3-iminobutanenitrile (3) in EtOH/AcONa. 3-Aminopyrazole derivative 5 was obtained upon reaction of 4 with hydrazine hydrate. Diazodization of 5 afforded the d
