实验步骤: 1-Isothiocyanato-2-methoxy-benzene (0.76 mL, 5.45 mmol) was added to a solution of 2-amino-4-methyl-benzoic acid methyl ester (900 mg, 5.45 mmol) and acetic acid (1.5 mL) in ethanol (10 mL), and heated at reflux for 16 hr. The reaction mixture was cooled to room temperature and diluted with ethanol. The precipitated solid was filtered, washed with ethanol and dried to afford 2-mercapto-3-(2-methoxy-phenyl)-7-methyl-3H-quinazolin-4-one (1.0 g, 62%) as white solid. heated at reflux for 16 hr The precipitated solid was filtered washed with ethanol dried
