Reaction Conditions

Reaction Steps

Benzyl bromide (0.80 mL) was added to a mixture of benzyl 4-benzoyloxy-2-hydroxybenzoate (2.23 g) and cesium carbonate (2.29 g) in N,N-dimethylformamide (10 mL) at room temperature. The mixture was stirred at 50° C. for 3 hrs, and water was added. The resulting mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by medium-pressure liquid silica gel column chromatography (eluent: n-hexane/ethyl acetate=6/1) to afford benzyl 4-benzoyloxy-2-benzyloxybenzoate (2.87 g).
