A simple and highly efficient protocol for the regioselective synthesis of azole-substituted imidazo[1,2-a]pyridines has been developed using a ligand-free, copper-catalyzed Ullmann-type C-N coupling of 2-(2-bromophenyl) imidazo[1,2-a]pyridines with different azoles and in situ generated 1,2,3-triazoles. The reactions proceeded smoothly to furnish azolo-imidazo[1,2-a]pyridines in good to excellent yields (65-96%). Georg Thieme Verlag Stuttgart New York.
