실험 절차

To a solution of 1-isopropyl-imidazolidine-2,4-dione (0.10 g, 0.70 mmol) in N,N-dimethylformamide (5 mL) was added sodium hydride (60% in mineral oil, 31 mg, 0.77 mmol) and the reaction mixture was stirred for 10 minutes. Then, 2-[4-(2-bromo-ethoxy)-3,5-dimethyl-phenyl]-5,7-dimethoxy-3H-quinazolin-4-one (0.32 g, 0.73 mmol) was added. The reaction mixture was stirred at 55° C. for 16 hours, then poured into water (100 mL). The solid was filtered and dried. The crude compound was purified by column chromatography (silica gel 230-400 mesh; eluting with 2:1 ethyl acetate and dichloromethane) to give the title compound as a white solid. Yield: 0.09 g (26.0%). MP 219-221° C. 1H NMR (400 MHz, DMSO): δ 9.64 (s, 1H), 7.69 (s, 2H), 6.82 (d, J=2.4 Hz, 1H), 6.45 (d, J=2.4 Hz, 1H), 4.42 (m, 1H), 4.02 (m, 2H), 3.98 (m, 2H), 3.96 (s, 3H), 3.92 (s, 3H), 3.85 (s, 2H), 2.32 (s, 6H) 1.22 (d, J=6.4 Hz, 6H). MS (ES+) m/z: 495.16 (M+1).
