The resulting solution was stirred at reflux for 2 h, diluted with water, and extracted with EtOAc. The aqueous layer was neutralized with saturated NaHCO3 solution and extracted with EtOAc. The combined extracts were dried over MgSO4, filtered, and concentrated. The crude product (364 mg, 58% yield) was used for the next step without purification.
