The contents of the vials were combined and were diluted with 400 mL water and extracted with five 150 mL portions of ethyl acetate. The combined extracts were dried over sodium sulfate, and the solvent was removed in vacuo. The crude residue was purified by flash column chromatography to yield the desired product (1.40 g, 59%).
