To the reaction mixture was added 1N hydrochloric acid (1.0 mL), and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (63 mg) as a colorless oil.
