The reaction mixture was stirred at 0 C. for 40 minutes. After this time, the reaction was quenched with saturated sodium bicarbonate solution (PH?8) and extracted with dichloromethane for three times. The combined extracts were washed once with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The crude residue was purified by flash chromatography (silica gel) to give the desired product as red solid.
