The reaction mixture was poured into a separatory funnel containing 150 ml water and extracted 3×100 mls with ethyl acetate. The combined organics were washed with 100 ml 10% KOH, and brine, dried with anhydrous MgSO4 and concentrated. The residue was recrystallized from 70% ethyl acetate in hexane yielding 9.5 g product.
