反応手順

To a solution of 3-phenoxyphenyl methanol (4.0 g, 0.020 mol) in anhydrous acetonitrile was added 1-bromo-2,5-pyrrolidinedione (3.73 g, 0.021 mol) at room temperature. The mixture was stirred at room temperature for one and a half hour under an atmosphere of nitrogen. The solvents were removed under the reduced pressure. Tetrachloromethane (100 mL) was added to the residue, and the mixture was filtered. The filtrate was concentrated into the residue, and the residue was purified by flash chromatography on silica gel using ethyl acetate/n-heptane (1:5) as mobile phase to yield (2-bromo-5-phenoxyphenyl)methanol (4.7 g, 0.017 mol):
