3-Amino-4,6-dimethylpyrazolo[3,4-b]pyridine was used for the preparation of some novel heterocycles of pharmaceutical interest. The starting material reacted with 2-cyano-3,3-bis(methylthio)acrylate, chloroacetyl chloride, phenyl isothiocyanate, carbon disul-fide, and aromatic aldehydes to give the novel heterocycles. The structures of the hitherto unknown ring systems have been confirmed by analytical and spectral methods.

3-amino-4,6-dimethylpyrazolo[3,4-b]pyridine is a promising starting material for the synthesis of novel pharmaceutical heterocycles with structures confirmed by analytical and spectroscopic methods.
