The mixture was cooled to room temperature, diluted with brine, and extracted with ethyl acetate (30 mL×3). The organic layers were combined and washed with brine. The solvent was dried over sodium sulfate and removed under reduced pressure to give a residue which was purified by column chromatography on silica gel to give 119 mg of product as a white solid.
