The mixture was hydrogenated on a Parr hydrogenator overnight. The reaction mixture was filtered through Celite and washed with dichloromethane. The filtrate was evaporated to brown oil. The oil was dissolved in dichloromethane, washed with 10% sodium hydroxide, dried over magnesium sulfate, filtered, evaporated to a brown oil. The oil was purified using a 200 g Varian column eluting with 10% ethyl acetate/hexanes. 6.55 g (34% yield) of product was obtained.
