The solution was diluted with 70% ethyl acetate (hexanes), washed three times with 1M aqueous HCl, washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was purified by flash column chromatography on silica gel using 10% ethyl acetate (hexanes) to yield the title compound.
