Lithium borohydride (22 0mg) was added in a single portion to a stirred solution of methyl 3-bromo-5-(trifluoromethyl)benzoate (2.46 g) in ether (60 ml) containing water (156 ml). The resulting solution was stirred for 4 hours at room temperature, at which point the reaction mixture was diluted with saturated aqueous NH4Cl solution (50 ml). The organic layers were separated, dried over MgSO4, filtered and the solvent removed under reduced pressure to give 3-bromo-5-(trifluoromethyl)benzyl alcohol as a clear oil (2.1 g).1H NMR (360 MHz,CDCl3) δ 1.83 (1H, br s), 4.76 (2H,s), 7.47 (1H, s), 7.56 (1H, s), 7. 68 (1H, s).
