The product of Example 3 Step 2 (191 mg, 0.668 mmol, 1.00 equiv), the product of Step 2 (125 mg, 0.668 mmol, 1.0 equiv), and EDC (153 mg, 0.802 mmol, 1.20 equiv) were suspended in 2.0 mL DMF. Et3N (0.112 mL, 0.802 mmol, 1.2 equiv) was added and the solution was stirred at room temperature for 18 hrs. The reaction mixture was diluted with EtOAc and 1N HCl. The phases were separated, and the organic phase was washed twice with 1N HCl, once with satd. NaHCO3, and once with satd. NaCl. The organic phase was dried over Na2SO4, filtered, and concentrated en vacuo. The residue was purified by reverse-phase HPLC (20-90% CH3CN/H2O—NH4OH to pH 10 over 13 minutes, retention time 7.79 min) to provide 20 mg (7%) of the title compound as a white solid. MS (ES+) m/e 452 [M+H]+
