(Diethylamino)sulfur trifluoride → 3-{[4-(4-Acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenyl]-fluoro-methyl}-benzonitrile

Participants

Reaction Steps

A solution of 3-{[4-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenyl]-hydroxy-methyl}-benzonitrile (5.0 g, 12.06 mmol) and dichloromethane (100 mL) is stirred at −78° C. Diethylaminosulfur trifluoride (1.8 mL, 13.74 mmol) is added, the cold bath is removed, and the reaction is stirred at room temperature 1 hr. The reaction mixture is diluted with water (100 mL), the layers are separated, and the aqueous layer is extracted with dichloromethane (2×100 mL). The organic layers are combined, washed with water (50 mL), dried over magnesium sulfate, filtered, and concentrated to give 5.1 g, 100%, of the title compound as a tan solid. LCMS M+1=418.
