To a stirred solution of 2,2,2,4′-tetrafluoroacetophenone (10 g, 52.1 mmol) in methanol (50 mL) was added NaBH4 (0.98 g, 26.5 mmol) at 0° C. After stirring at 25° C. for 2 h, the reaction mixture was quenched by adding 1N HCl (100 mL) and then extracted with ethyl ether. The ether extract was washed with brine, dried with MgSO4, and concentrated to give 2,2,2-trifluoro-1-(4-fluorophenyl)ethanol (11.32 g) which was used in next step without further purification.
