The reaction was quenched with methanol, and the solvents were removed under reduced pressure. 5 mL of saturated NH4Cl water solution and 10 mL of dichloromethane were added to the residue. The dichloromethane layer was dried over MgSO4, filtered, evaporated, and purified by column chromatography (ethyl acetate:MeOH=10:1) to give the product (i.e., Compound 7) as a white solid (0.14 g, 48%). cooled in an ice bath cooled in ice bath the mixture was stirred at room temperature for additional 4 hours The reaction was quenched with methanol the solvents were removed under reduced pressure 5 mL of saturated NH4Cl water solution and 10 mL of dichloromethane were added to the residue The dichloromethane layer was dried over MgSO4 filtered evaporated purified by column chromatography (ethyl acetate:MeOH=10:1)
