An environmental friendly, efficient protocol has been realized for the synthesis of N-pyridinylamides via copper catalyzed oxidative amidation of arylalkylketones with 2-aminopyridines. This one pot protocol involves chemo selective cleavage of C (O)–C bond in the presence of singlet oxygen. The reaction conditions are simple, tolerates wide range of substrates and the products were formed in good
