Reaction Steps

Methyl (3-(2-(2-phenylethylthio)ethyl)-2-methylbenzofuran-7-yloxy)acetate (340 mg) was dissolved in methanol (15 ml) and the obtained solution was cooled to −10° C. To this solution, NBS (190 mg) was added for 5 minutes and the resulting mixture was stirred at −10° C. for 30 minutes. This reaction solution was poured into water layer (100 ml) and the resultant was extracted twice with ethyl acetate (30 ml). The organic layers were combined and washed with saturated brine, followed by drying over sodium sulfate. After removing the sodium sulfate by filtration, the solvent was removed under reduced pressure and the residue was purified by column chromatography (solvent: dichloromethane/ethyl acetate=2/1) using silica gel to obtain the desired compound (225 mg, yield: 64%).
