A ‘one-pot’ method has been developed for the synthesis of azoquinazolinones from substituted 2-halo-benzamides and different N-heterocycles via Cu(I)-catalyzed C–N coupling/C–H activation/C–N formation process under O2. A number of azoquinazolinones containing different azole rings and substituents were obtained in good yields.
