Procedure: 2,4-Difluorobenzaldehyde (1.1 mL, 10.0 mmol) and (trifluoromethyl)trimethylsilane (1.77 mL, 12.0 mmol) were dissolved in THF (25 mL) and then cooled to 0° C. To this, 1M TBAF in THF (76 μL, 76 μmol) was added and the reaction mixture was allowed to warm to room temperature. After 3.25 h, 2.5M HCl (25 mL) was added. The reaction was stirred for 1 h and then extracted with ether. The organic layer was washed with brine and dried with Na2SO4. The solvent was removed under the reduced pressure to give 2,2,2-trifluoro-1-(2,4-difluoro-phenyl)ethanol (2.5 g) as a racemic mixture. to warm to room temperature extracted with ether The organic layer was washed with brine dried with Na2SO4 The solvent was removed under the reduced pressure
