After 4 h, the reaction mixture was partitioned between water and ethyl acetate. The organic layer was separated and the aqueous layer was extracted again with ethyl acetate. The combined organic layer was washed with brine and dried over sodium sulfate, filtered and concentrated to a white solid. Trituration with diethyl ether provided the title compound as a white solid (365 mg, 75%).
