Procedure

A solution of Example 91C (51.5 mg, 0.155 mmol), N-hydroxybenzotriazole monohydrate (34.5 mg, 0.225 mmol), 4-methylmorpholine (47 mg, 0.464 mmol) and NH4Cl (31.6 mg, 0.591 mmol) in DMF (1 mL) at 0° C. was treated with EDC (45.0 mg, 0.235 mmol), stirred at 0° C. for 4 hours and at room temperature for 10 hours, treated with chloroform (5 mL), washed sequentially with 1M NaHCO3 and brine, dried (Na2SO4), filtered, and concentrated. The residue was purified by flash chromatography on silica gel with 5% methanol/dichloromethane to provide the title compound.
