Procedure

A solution of the product from Example 6A (0.046 g, 0.119 mmol) in THF (0.9 mL) was treated with the product from Example 7B (0.050 g, 0.119 mmol), EDAC (0.035 g, 0.183 mmol), HOBT (0.025 g, 0.185 mmol), and NMM (0.040 mL, 0.364 mmol) at 0° C., stirred at 25° C. for 16 hours, and partitioned between ethyl acetate and water. The organic phase was washed with 10% citric acid, dilute sodium bicarbonate solution, and brine, dried over MgSO4, filtered and concentrated. The residue was purified by reversed phase chromatography on a C18 column, eluting with 5-100% acetonitrile in water (0.1% TFA) to give the title compound (0.080 g, 100% yield).
