実験手順

To a solution of 2-amino-4,6-dimethoxy-benzamide (150 mg, 0.76 mmol) and 4-morpholin-4-ylmethyl benzaldehyde (156 mg, 0.76 mmol) in N,N-dimethyl acetamide (10 mL), NaHSO3 (150 mg, 0.84 mmol) and p-TSA (174 mg, 0.91 mmol) were added and the reaction mixture was heated at 150° C. for 5 h. The reaction mixture was cooled to room temperature, water was added and the mixture was neutralized with NaHCO3. The solvent was removed under reduced pressure to give the crude product, which was purified by column chromatography to give 5,7-dimethoxy-2-(4-(morpholinomethyl)phenyl)quinazolin-4(3H)-one, which was converted to the hydrochloride salt (165 mg, 51%). Selected data: MS (ES) m/z: 382.07; MP 206-208° C. (at decomposition).
