An efficient Cu(II)-vasicine catalytic system has been developed for intramolecular C[sbnd]N bond formation. In this way, regioselective 2-amination of o-haloanilides with aqueous ammonia in EtOH has been achieved. This strategy provides several advantages, such as good regioselectivity, high yields and functional group tolerance.
