Participants

Reaction Steps

To 3-{[4-(4-acetyl-3-hydroxy-2-trifluoromethyl-phenoxymethyl)-phenyl]-hydroxy-methyl}-benzonitrile (211 mg, 0.48 mmol) in anhydrous CH2Cl2 (5 mL) at room temperature under Ar is added Et3SiH (0.61 mL, 3.8 mmol) and BF3.ether complex (0.12 mL, 0.96 mmol). The reaction mixture is stirred at room temperature for 2 h and quenched into saturated aqueous NH4Cl (20 mL). The aqueous mixture is extracted with CH2Cl2 (3×25 mL). The organic layers are combined, washed with brine, dried over sodium sulfatesodium sulfate, and concentrated. The residue is purified by flash column chromatography using 50% ethyl acetate/hexane as eluent to give the title compound (108 mg, 53%). LC-MS (m/e): 424 (M−1)
