Methanol → HCID 53784183, compound

Participants

Reaction Steps

7-acetoxy-3-((acetylamino)methyl)benzofuran (258 mg) and potassium carbonate (82 mg) were added to methanol (5 ml) and the obtained mixture was stirred at room temperature for 1 hour. After removing methanol under reduced pressure, DMF (5 ml) and methyl bromoacetate (0.15 ml) were added to the residue, followed by stirring the resultant for 18 hours. The reaction solution was poured into water layer (30 ml) and the resultant was extracted twice with ethyl acetate (20 ml). The organic layers were combined and washed with saturated brine, followed by drying over anhydrous 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: chloroform/methanol=95/5) using silica gel to obtain the desired compound (227 mg, yield: 78%).
