A novel, catalyst-free photoinduced synthesis of 2,4-substituted quinazoline using 2-amino-aryl ketone, an aldehyde, and ammonium acetate was developed. A series of 2,4-substituted quinazoline compounds were obtained via irradiating the reactants with a light-emitting diode light (18 W) at roomtemperature. The broad substrate range and excellent gram-scale experimental results demonstrate the versatility
