Abstract In this work we present a new method for indazole synthesis through the unexpected rearrangement of various 7‐nitroisatins during reaction with hydrazine hydrate. The pyrazole cycle is formed via direct metal‐free C−H amination. We demonstrate limitations discovered approach and several accessible methods functionalization compounds to obtain novel derivatives.
