To an ice-cooled mixture of 4-methoxythiophenol (15 g, 0.11 mol), triethylamine (28 mL, 0.20 mol) and tetrahydrofuran (150 mL) was added ethyl bromoacetate (21 g, 0.13 mol), and the mixture was stirred overnight at room temperature. Ethanol (10 mL) was added, the solvent was evaporated under reduced pressure, and the residue was partitioned between ethyl acetate and water. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10:1) to give title compound (22 g, yield 92%). oil.
