To a solution of 3-(3-(trifluoromethoxy)phenyl)prop-2-yn-1-ol (0.3 g, 1.39 mmol) in THF (10 mL) was added LAH (63 mg, 1.68 mmol) portionwise at 0° C. The reaction was stirred at 0° C. for 3 h. The reaction was carefully quenched by dropwise addition of ethyl acetate at 0° C. and the mixture was partitioned between ethyl acetate and water. The combined organic layer was dried over sodium sulfate, filtered and concentrated to give a crude product which was purified by column chromatography eluting with ethyl acetate/petroleum ether (1:4 to 1:1) to give 3-(3-(trifluoromethoxy)phenyl)propan-1-ol (0.26 g, 85.2%) as a yellow oil which was used without purification. 1H-NMR (CD3OD) δ 7.37-7.39(d, 1H), 7.31-7.35(m, 1H), 7.15-7.17 (d, 1H), 4.07-4.11(t, 2H), 2.72-2.76(t, 2H), 1.83-1.90(m, 2H).
