Reaction Steps

To a solution of 5,7-dimethoxy-2-(4-(piperazin-1-yl)phenyl)quinazolin-4(3H)-one (0.150 g, 0.40 mmol) in CH2Cl2 (10 mL) was added Et3N (0.08 mL, 0.60 mmol), and cyclopropane carbonyl chloride (0.03 mL, 0.36 mmol). The resulting solution was stirred overnight at room temperature. The solution was concentrated in vacuo and the material was purified by flash chromatography on silica gel eluting with 0% to 50% of 92:7:1 CHCl3/MeOH/concentrated NH4OH in CH2Cl2 to afford the title compound (0.100 g, 63%). 1H NMR (300 MHz, DMSO-d6): δ 11.78 (s, 1H), 8.12 (d, J=8.9 Hz, 2H), 7.04 (d, J=9.2 Hz, 2H), 6.63-6.74 (m, 1H), 6.39-6.52 (m, 1H), 3.73-3.95 (m, 8H), 3.51-3.73 (m, 2H), 3.21-3.49 (m, 4H), 1.93-2.10 (m, 1H), 0.56-0.83 (m, 4H). APCI MS m/z 435 [M+H]+.
