A facile, efficient, and simple protocol for direct oxidative C–H amination of benzoxazoles with primary amines through copper-catalyzedC–H bond activation using tert -butyl peroxide (TBP) as oxidant under air has been developed. The reaction proceeds smoothly at ambient temperature to furnish the products. A variety of substituted aminobenzoxazoles were synthesized with good to excellent yields.
