A copper‐catalyzed intramolecularamidation of unactivated C(sp3)−H bonds to construct indoline derivatives has been developed. Such an amidation proceeded well at primary C−H bonds preferred to secondary C−H bonds. The transformation owned a broad substrate scope. The corresponding indolines were obtained in good to excellent yields. N‐Formal and other carbonyl groups were suitable and were easily
