Reaction Conditions

Reaction Steps

(5-Bromo-4′-fluorobiphenyl-3-yl)methanol (0.42 g, 1.5 mmol) and triphenylphosphine (0.78 g, 2.98 mmol) were combined in tetrahydrofuran (8 mL) and cooled to 0° C. N-Bromosuccinimide (0.59 g, 3.1 mmol) was introduced in portions and the reaction allowed to warm to room temperature. After 16 h, the reaction mixture was diluted with ethyl acetate, washed with concentrated sodium bicarbonate (2×), then brine (2×), dried over sodium sulfate, and concentrated. Column chromatography on silica gel (5% ethyl acetate/hexanes) gave 0.4 g (78%) as a white powder. 1H-NMR (CDCl3, 500 MHz) 7.60 (m, 1H), 7.50-7.54 (m, 3H), 7.47 (m, 1H), 7.12-7.15 (m, 2H), 4.47 (s, 2H).
