A mixture of 2-amino-4,6-dimethoxybenzamide (0.15 g, 0.765 mmol), 4-morpholin-4-yl-benzaldehyde (0.15 g, 0.765 mmol), sodium hydrogensulfite (0.136 g, 0.765 mmol) and p-toluenesulfonic acid (10 mg) in N,N-dimethyl acetamide (10 mL) was stirred at 155° C. for 14 h. The reaction mixture was cooled to room temperature and diluted with water (50 mL). The solid was collected by filtration, washed with water and MeOH to yield 5,7-dimethoxy-2-(4-morpholinophenyl)quinazolin-4(3H)-one (0.109 g, 39%).
