Reaction Steps
To a solution of 5,7-dimethoxy-2-(4-(piperazin-1-yl)phenyl)quinazolin-4(3H)-one (0.200 g, 0.54 mmol) in THF (10 mL) was added EDCl (0.105 g, 0.54 mmol), HOBt (0.074 g, 0.54 mmol), Et3N (0.08 mL, 0.54 mmol) and trifluoropropionic acid (0.070 g, 0.54 mmol). The reaction was stirred at room temperature for 4 hours and concentrated in vacuo. Purification by flash chromatography, eluting with 20% to 100% of 92:7:1 CHCl3/MeOH/concentrate NH4OH in CH2Cl2, afforded the title compound (0.135 g, 52%). 1H NMR (300 MHz, DMSO-d6): δ 11.78 (s, 1H), 8.10 (d, J=9.0 Hz, 2H), 7.03 (d, J=9.0 Hz, 2H), 6.68 (d, J=2.3 Hz, 1H), 6.47 (d, J=2.3 Hz, 1H), 3.88 (s, 3H), 3.83 (s, 3H), 3.70-3.78 (m, 2H), 3.60-3.67 (m, 4H), 3.34-3.38 (m, 4H). APCI MS m/z 477 [M+H]+.
