The reaction mixture was poured into water (100 ml) and extracted with methylene chloride (3×100 ml). The organic layer was washed with water (3×150 ml), dried over anhydrous sodium sulfate, filtered and the solvent was removed under vacuum. Chromatography (5% methanol-methylene chloride) afforded 0.27 g (43%) of product as a brown oil.
