A Rh(III)‐catalyzed intermolecular unactivated secondary C(sp3)−H bond amidation via nitrene insertion directed by 3,5‐dimethylpyrazole is reported. This procedure tolerates a broad substrate scope including chain and cyclic N‐alklyamides. Notably, the directing group 3,5‐dimethylpyrazole of chain N‐alkylamide substrates could be easily removed via cascade intermolecular amidation and intramolecular cyclization in one‐pot affording the sulfonylureas by increasing the reaction temperature.
