Procedure

To a suspension of Example 131D (70mg, 0.22 mmol) in anhydrous tetrahydrofuran (5 mL) under nitrogen atmosphere was added 1,1-carbonyldiimidazole (71mg, 0.44 mmol) and triethylamine (60 [μL, 0.44 mmol). The reaction mixture was stirred at reflux for 48 hours and then ambient temperature for an additional 24 hours. The reaction mixture was poured into a 1:1 solution of water: saturated NH4Cl and the resulting solid collected by filtration. This material was purified by flash chromatography on silica gel eluting with 20% acetone-hexane. The desired fractions were combined, evaporated and slurried in hot EtOAC to obtain title compound (39 mg) in 51% yield.
