New Heterocyclo-Substituted Pyrazolo[3,4-b]pyridine Derivatives

Abstract

In this investigation and in continuance with our previous work in the synthesis of some heterocyclic compounds fused with pyridine moiety, we used 3-amino-4,6-diphenyl-1H-pyrazolo[3,4-b]pyridine (II) as starting material to synthesize many heterocyclic compounds containing pyrazolopyridine moiety.
