Procedure

Stir a mixture of 2-iodobenzyl bromide (90 g, 0.29 mol), 2-bromo-5-fluorophenol (57.9 g, 0.29 mol), and potassium carbonate (63 g, 0.46 mol) in N,N-dimethylformamide (750 mL) at room temperature for 16 h. Add water (1 L), stir the resulting mixture for one hour, filter off solids, rinse with water and dry in a vacuum oven (20 mm Hg/60° C.) to obtain the title compound (121 g, >100%). 1H NMR (400 MHz, DMSO-d6) δ 5.11 (s, 2H), 6.81 (t, 1H), 7.13 (t, 1H), 7.19 (dd, 1H), 7.46 (t, 1H), 7.59 (d, 1H), 7.62 (t, 1H), 7.93 (d, 1H).
