Abstract

In this paper, exploration of our continuous interests on late-stage derivation of quinozaline core is described. A wide array of 4-(1H-indol-1-yl)quinazolines were obtained in good to excellent yields through palladium-catalyzed cross-coupling of 4-tosyloxyquinazolines with indole derivatives under mild reaction conditions.
