실험 절차
A solution of the crude product of Step 1 (36.5 g, 188 mmol) in chloroform (500 ml) was treated over 30 min with phosphorus trichloride (80 g, 580 mmol) at 0°, heated under reflux for 1 h, cooled to room temperature, and poured onto ice (2 Kg). The mixture was basified with sodium hydroxide and the layers separated. The aqueous phase was extracted with chloroform (500 ml).
