실험 절차

To a stirred solution of 2-chloro-6-methylquinazolin-4(3H)-one (15 g, 77.3 mmol) and 2,3,4,5-tetrahydro-1,4-benzothiazepine 1-oxide (16.8 g, 103 mmol) in toluene (200 mL) was added triethylamine (16.1 mL, 116 mmol). After being refluxed overnight, the reaction mixture was cooled to room temperature. The formed solid was collected by filtration, washed with ethanol (50 mL) and ethyl acetate (100 mL), and then dried in vacuo to afford 21.0 g of the desired product as a white solid (yield was 80%).
