A solution of ethyl (4-hydroxyphenoxy)acetate (0.49 g, 2.5 mmol), 4-phenylbutyl bromide (0.59 g, 2.8 mmol), potassium carbonate (0.69 g, 5.0 mmol) and potassium iodide (30 mg, 0.50 mmol) in N,N-dimethylformamide (5 mL) was stirred at room temperature for 30 min., and further at 50° C. for 3 hrs. The solvent was evaporated under reduced pressure, and the residue was partitioned between ethyl acetate and saturated brine. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4:1) to give the title compound (0.62 g, yield 76%). oil.
