반응 단계
To a stirred suspension of (3-fluoro-4-methanesulfonyl-phenyl)-methanol (0.269 g, 1.31 mmol) in diethyl ether (5 ml) under an inert atmosphere of Argon is added dropwise phosphorus tribromide (46 μl, 0.434 mmol). After stirring at room temperature overnight, the reaction mixture is diluted with water (2 ml) and the diethyl ether layer separated. This organic portion is placed over NaOH pellets and after 20 minutes, is used as a reagent in solution in diethyl ether.
