실험 절차
A solution of N-benzyl-N-(1-(5-(5,7-dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)pyridin-2-yl)piperidin-4-yl)acetamide (0.200 g, 0.39 mmol) in 2 N HCl (15 mL) was refluxed for 3 days. The resulting mixture was basified with 2 N NaOH and extracted with CH2Cl2. The organics were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. Purification by flash chromatography on silica gel, eluting with 10% to 100% of 92:7:1 CHCl3/MeOH/concentrated NH4OH in CH2Cl2, afforded the title compound (0.110 g, 60%) as a white solid. 1H NMR (300 MHz, DMSO-d6): δ 11.11 (br s, 1H), 8.89 (d, J=2.3 Hz, 1H), 8.22-8.26 (m, 1H), 7.28-7.37 (m, 4H), 7.18-7.23 (m, 1H), 6.91 (d, J=7.2 Hz, 1H), 6.67 (d, J=2.2 Hz, 1H), 6.46 (d, J=2.2 Hz, 1H), 4.27-4.31 (m, 2H), 3.88 (s, 3H), 3.83 (s, 3H), 3.76 (s, 2H), 3.00-3.11 (m, 2H), 2.62-2.69 (m, 1H), 1.88-1.91 (m, 2H), 1.25-1.31 (m, 2H).
