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-1<i>H</i>-pyrazolo[3,4-<i>b</i>]pyridine (<i>II</i>) as starting material to synthesize many heterocyclic compounds containing pyrazolopyridine moiety.
