Reaction Steps

To a solution of 5,7-dimethoxy-2-(4-(piperazin-1-yl)phenyl)quinazolin-4(3H)-one (0.120 g, 0.32 mmol) in CH2Cl2 (10 mL) was added Et3N (0.06 mL, 0.48 mmol) and hexanoyl chloride (0.03 mL, 0.28 mmol). The resulting solution was stirred at room temperature for 1 hour. The mixture was concentrated in vacuo. The material was purified by flash chromatography, eluting with 2% to 10% of MeOH/CH2Cl2, to afford the title compound (0.050 g, 38%). 1H NMR (300 MHz, DMSO-d6): δ 11.79 (s, 1H), 8.11 (d, J=8.7 Hz, 2H), 7.03 (d, J=8.8 Hz, 2H), 6.68 (s, 1H), 6.47 (s, 1H), 3.75-4.05 (m, 6H), 3.47-3.73 (m, 4H), 3.17-3.43 (m, 4H), 2.20-2.40 (m, 2H), 1.41-1.62 (m, 2H), 1.15-1.38 (m, 4H), 0.76-0.98 (m, 3H); APCI MS m/z 465 [M+H]+.
