Reaction Steps

To a solution of 4-amino-1-(3-fluorobenzyl)pyridin-2(1H)-one (0.263 g, 1.2 mmol) in acetonitrile (7 mL) was added a DMAP (ca.), triethylamine (0.25 mL, 1.8 mmol) and 4-fluorobenzoyl chloride (0.213 mL, 1.8 mmol). The reaction mixture stirred at 0° C. for 25 minutes and then filtered. The solid was washed with 10% citric acid and water to afford the desired compound (0.326 g, 79%) after drying. 1H-NMR (d6DMSO, 400 MHz) δ 7.98 (m, 2H), 7.71 (d, 1H, J=7.6 Hz), 7.35 (m, 3H), 7.08 (m, 3H), 6.98 (d, 1H, J=2.4 Hz), 6.61 (dd, 1H, J=2.4 Hz, 2.4 Hz), 5.03 (s, 2H); ESLRMS m/z 341.1.
