The mixture was cooled to room temperature and diluted with ethyl acetate (10 mL), and then washed with water (10 mL). The organic layer was dried over sodium sulfate and evaporated to give a residue which was purified by column chromatography on silica gel to give 222 mg of product as a white solid (yield was 41%).
