The two layers were separated and the aqueous phase was extracted with dichloromethane. The combined organic extracts were dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by flash silica chromatography eluting with 50% ethyl acetate in isohexane to give the sub-title compound as a white solid (1.8 g).
