Reaction Steps
The product from Example 24A (104 mg, 0.444 mmol) and triethylamine (0.095 mL, 0.68 mmol) were combined in DMF (3 mL) and treated with diphenylphosphoryl azide (0.14 mL, 0.65 mmol). After stirring for 4 hours, the mixture was treated with water (0.30 mL) and heated at 65° C. for 1 hour. The mixture was allowed to cool to room temperature, diluted with water (7 mL), and extracted with diethyl ether (7 mL). The organic layer was washed with brine (7 mL), dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (50% ethyl acetate in hexanes) to provide the title compound.
