2-c]quinazolines and imidazo[4,5-c]quinolines. The reaction involves a copper-catalyzed reductive amination through azidation followed by reduction and oxidative amination of C(sp3)–H bonds of N,N-dimethylacetamide in the presence of TBHP (tert-butylhydroperoxide) as oxidant. The method uses the easily available sodium azide as a nitrogen source and DMA (N,N-dimethylacetamide) as a one-carbon source for the
