3-Bromo-2-methylbenzoic Acid → (3-Bromo-2-methylphenyl)methanol

To a solution of 3-bromo-2-methyl benzoic acid (35 g, 160 mmol) in THF (200 mL) was added borane THF complex (1.0 M, 210 mL, 210 mmol). The mixture was allowed to stir for 24 hours. The reaction was quenched with water. The solvent THF was removed under reduced pressure. The resulting solid was dissolved in ethyl acetate (500 mL), washed with 1N hydrochloric acid, saturated sodium bicarbonate, and brine. The combined organic layers were dried over sodium sulfate and concentrated to afford (3-bromo-2-methylphenyl)methanol.
