Reaction Steps

Methyl (3-(2-(benzylsulfonylamino)ethyl)benzofuran-7-yloxy)acetate (143 mg) was dissolved in DMF (3 ml), and potassium carbonate (49 mg) and benzyl bromide (0.13 ml) were added to the obtained solution, followed by stirring the resulting mixture at room temperature for 27 hours and then at 50° C. for 14.5 hours. The reaction solution was poured into water layer (50 ml) and the resultant was extracted twice with ethyl acetate (20 ml). The organic layers were combined and washed with 1N hydrochloric acid and 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: hexane/ethyl acetate=2/1-1/1) using silica gel to obtain the desired compound (100 mg, yield: 57%).
