Reaction Steps

To a solution of Example 59C (0.5 g, 1.554 mmol) in 20 mL tetrahydrofuran, was added sodium hydroxide (0.249 g, 6.22 mmol) and the mixture was stirred at room temperature for 1 hour. p-Toluenesulfonyl chloride (0.355 g, 1.865 mmol) and benzyltriethylammonium chloride (0.018 g, 0.078 mmol) were added and the mixture was stirred for 12 hours. Water was added and the mixture was extracted with dichloromethane. The organic layer was washed with water and brine, dried over sodium sulfate, filtered, and concentrated to afford the crude product which was purified by column chromatography (100-200 silica-gel in hexane and eluted with 15% ethyl acetate-hexane) to afford the title compound. LCMS: 475.1 (M+H)+.
