Water was added to the reaction mixture, acidified with 1 M hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give the title compound (0.214 g, yield 58%) as colorless prism crystals.
