(4-氟-3-(甲基磺酰基)苯基)甲醇

反应条件: temp:85.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: (Step 1) Triphenylphosphine (3.21 g) was suspended in acetonitrile (50 ml), bromine (0.64 ml) was added, and the mixture was stirred for 30 min. [4-Fluoro-3-(methylsulfonyl)phenyl]methanol (2.5 g) was added to the reaction mixture, and the mixture was stirred at 85° C. for 20 hr, treated with aqueous sodium hydrogen carbonate solution, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by basic silica gel chromatography (ethyl acetate:hexane=1:1) to give 4-(bromomethyl)-1-fluoro-2-(methylsulfonyl)benzene (1.64 g). was added to the reaction mixture extracted with ethyl acetate The extract was washed with saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure The obtained residue was purified by basic silica gel chromatography (ethyl acetate:hexane=1:1)
