A commercially available Ru3(CO)12/Xantphos/t-BuOK catalyst system enables a straightforward ruthenium-catalyzed dehydrogenative synthesis of 2-arylquinazolines. Various 2-aminoaryl methanols were efficiently converted in combination with different types of benzonitriles into the desired products in good yields. The synthetic protocol offers operational simplicity, high atom efficiency and broad substrate scope.
