Procedure

To a mixture of 1-(3-fluorobenzyl)-4-hydroxy-3-iodopyridin-2(1H)-one (0.5 g, 1.44 mmol) in DMF (5 mL) was added K2CO3 (0.199 g, 1.44 mmol) followed by the addition of 4-fluorobenzyl bromide (0.189 mL, 1.51 mmol). The reaction mixture stirred at room temperature for 30 minutes. The mixture was diluted with ethyl acetate (50 mL) and washed with water. The organic extracts were dried over anhydrous Na2SO4 and concentrated to dryness. 1H-NMR (CD3OD, 400 MHz) δ 7.75 (d, 1H, J=7.6 Hz), 7.49 (q, 2H), 7.34 (q, 1H), 7.11 (m, 5H), 6.40 (d, 1H, J=7.6 Hz), 5.26 (s, 2H), 5.19 (s, -2H); ES-HRMS m/z 454.0098 (M+H calculated for C19H15NO2F2I requires 454.0110).
