A simple and efficient, ligand-free copper-catalyzed approach to quinazoline derivatives uses readily available substituted (2-bromophenyl)methylamines and amides as starting materials. The cascade reaction includes a sequential Ullmann-type coupling and aerobic oxidation and provides a convenient and practical strategy for the synthesis of quinazoline derivatives.
