The mixture was poured into water and extracted twice with ether. The ether layer was dried over magnesium sulfate, filtered, and concentrated to give an oil. The crude product was dissolved in ethyl acetate and filtered through a short pad of silica gel. The filtrate was redried over magnesium sulfate, filtered and concentrated under vacuum to give 10 g (95%) of product as an oil.
