Synthesis, reactivity and 13C-NMR of 1H-pyrazolo[3,4-c]pyridine derivatives
The synthesis of various 1H-pyrazolo [.-c.]pyridines was reported. 3- Cyano derivatives were obtained from the corresponding nitro compounds by Sandmeyer Reaction using Na3[Cu(CN)4] at pH 1. The 13C-NMR data of this series were also described.
