4-Bromo-2-methylbenzoic acid → (4-Bromo-2-methylphenyl)methanol

Participants

Reaction Steps

Add borane-tetrahydrofuran complex (0.2 mol, 200 mL, 1.0 M solution) to a solution of 4-bromo-2-methylbenzoic acid (39 g, 0.18 mol) in tetrahydrofuran (200 mL). After 18 hours at room temperature, remove the solvent under the reduced pressure to give a solid. Purify by flash chromatography to yield the title compound as a white solid (32.9 g, 0.16 mol). 1H NMR (CDCl3): δ 1.55 (s, 1H), 2.28 (s, 3H), 4.61 (s, 2H), 7.18-7.29 (m, 3H).
