The mixture was stirred under an atmosphere of hydrogen for 18 hours. The mixture was filtered through diatomaceous earth and the filtrate evaporated to leave a colourless oil. The crude product was purified by chromatography eluting with 30-50% EtOAc in hexane to give the product as a colourless oil. M/z 194.
