Procedure

A mixture of 1-biphenyl-2-yl-2,2,2-trifluoro-ethanone (300 mg, 1.2 mmol), borane tetrahydrofuran complexes (1.2 ml, 1M in THF, 1.2 mmol) and S-2-methyl-CBS-oxazaborolidine (0.24 ml, 1M in toluene, 0.24 mmol) in THF (8 ml) was stirred at room temperature over night. Several drops of concentrated HCl were added and the mixture was stirred for 30 minutes. The product was purified by SiO2 chromatography (hexane/ethyl acetate=100/0 to 3/1) to give 290 mg of 1-biphenyl-2-yl-2,2,2-trifluoro-ethanol (96% yield).
