Potassium Carbonate → 3-(3-Bromophenylsulfanyl)propane-1-ol

3-Bromobenzenethiol (0.40 g) and potassium carbonate (0.44 g) were suspended in N,N-dimethylformamide (4.2 mL), 3-chloropropyl acetate (0.34 mL) was added, and the resulting mixture was stirred at 60° C. for 5 hours. The reaction mixture was partitioned between diethyl ether (40 mL) and water (10 mL). The organic layer was washed successively with water (10 mL×2) and brine (10 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was dissolved in methanol (8.5 mL), 28% sodium methoxide-methanol solution (0.08 mL) was added, and the resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure and the residue obtained was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=3/1) to give the title compound (0.49 g).
