A novel class of substituted quinazolines were prepared in good yields by a one-pot
three-component reaction of isocyanides with adducts of anilines and tri- or dichloroacetonitrile,
followed by intramolecular C–H activation, catalyzed by copper(I) iodide with l-proline as a ligand in acetonitrile at room temperature.
