  protocol for the synthesis of quinazolines in the absence of solvent and catalyst has been developed. 2,4‐Disubstituted quinazolines have been synthesized from three‐component one‐pot reactions of 2‐aminoaryl ketones, orthoesters, and ammonium acetate. The present method has advantages of operational simplicity, substrate generality, clean reaction, high yields (76–94%), and moderate reaction time. The plausible
