Synthesis of 7-aminopyrazolo[3,4-c]pyridine as a probe for the preparation of compounds of pharmacological interest

Article abstract of DOI:10.3987/com-02-9621

A synthetic route towards the preparation of 7-aminopyrazolo[3,4-c]pyridine is developed, starting from the readily accessible 2-amino-4-methyl-3-nitropyridine. The unexpected formation of 7-methylimidazolo[4,5-b]pyridin-2-one during the reaction sequence is also described.
