Procedure

To a solution of 1-(2-Trifluoromethoxyphenyl)ethanone (1.00 g, 4.90 mmol) in THF (5 mL) at 0° C. was added 1M LiAlH4 in THF (5.9 mL, 5.9 mmol), and the solution was allowed to warm to rt. A few drops of water were added to quench. The mixture was concentrated in vacuo, transferred to a separatory funnel, and extracted using DCM and sat. aq. Rochelle salt. The organic layer was concentrated in vacuo to afford the title compound as a clear oil.
