Synthesis of 7-Aminopyrazolo[3,4-c]Pyridine as a Probe for the Preparation of Compounds of Pharmacological Interest

摘要

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.
