Reaction Steps

To a solution of 5,7-dimethoxy-2-(4-(piperazin-1-yl)phenyl)quinazolin-4(3H)-one (0.200 g, 0.55 mmol) in DMF (5 mL) was added 4-fluorobenzyl bromide (0.07 mL, 0.55 mmol) and K2CO3 (0.15 g, 1.10 mmol). The reaction was stirred at room temperature for 2 hours then diluted with H2O and the solids filtered off to afford the title compound (0.17 g, 65%) as a light brown solid. 1H NMR (300 MHz, DMSO-d6): δ 11.76 (br s, 1H), 8.09 (d, J=8.1 Hz, 2H), 7.26-7.52 (m, 2H), 7.08-7.25 (m, 2H), 7.00 (d, J=8.0 Hz, 2H), 6.68 (s, 1H), 6.46 (s, 1H), 3.87 (s, 3H), 3.83 (s, 3H), 3.51 (s, 2H), 3.08-3.41 (m, 4H), 2.23-2.68 (m, 4H). APCI MS m/z 475 [M+H]+.
