PREPARATION 8 1-Bromo-3-fluorobenzyl bromide To a solution of 1-bromo-3-fluorobenzyl alcohol (1.61 kg, 7.85 mol) in chloroform (14 L) at 0° C. add pyridine (770 mL, 9.52 mol) in one portion (slight exotherm) and stir at 0° C. for 5 min. Add phosphorus tribromide (900 mL, 9.49) dropwise while maintaining the internal temperature below 20° C. and stir the resulting solution overnight while allowing to warm to room temperature. Cool the reaction to 0° C. and quench slowly with ice water (2 L). Transfer to a 50 L flask, separate the layers and then extract the aqueous layer with chloroform (1 L). Wash the combined organic phases with 5percent sulfuric acid (2 L), saturated aqueous sodium bicarbonate (2 L), brine (2 L), dry over magnesium sulfate, filter, and concentrate to obtain the title compound as a yellow oil (1753 g, 83percent). 1H NMR (CDCl3) delta 7.43 (d, 1H), 7.21 (m, 1H), 7.09 (t, 1H), 4.68 (s, 2H).
