Hydrogen was added (balloon) and the mixture was vigorously stirred for 4 hours. The reaction mixture was filtered, H2O was added, the mixture was extracted with ethyl acetate and the organic extracts dried and evaporated. Flash chromatography of the residue using 40% ethyl acetate/hexane afforded the title compound.
