Participants

Reaction Steps

2-(1,1-dimethyl-3-trifluoromethyl-3-trimethylsilanyloxyhex-5-ynyl)benzamide (108 mg, 0.28 mmol) was treated with a 1M solution of TBAF in 3 mL of THF. The reaction mixture was stirred for 1 hour then diluted with 50 mL of ethyl acetate, washed with 25 mL of 1 M aqueous HCl, two 25 mL portions of saturated aqueous sodium bicarbonate solution, dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude was purified by flash chromatography (12 g SiO2, hexanes to 1:1 hexanes:EtOAc) to give 2-(3-hydroxy-1,1-dimethyl-3-trifluoromethylhex-5-ynyl)benzamide as a white solid (82 mg, 93%). MS (ES+) m/z 314 [M+H]+.
