Reaction Steps

To a solution of the title compound of Example 15 Step B (0.02 mmol, 10 mg), 1H-tetraazol-5-amine monohydrate (0.2 mmol, 21 mg), HOBt (0.2 mmol, 31 mg) and DIEA (0.3 mmol, 52 μL) in 0.5 mL of DMF was added EDC (0.2 mmol, 38 mg). The reaction was heated to 40° C. 15 min, then allowed to stand at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure. The residue was taken up in ca. 2:1 dioxane/H2O and acidified with TFA, then purified by reverse-phase chromatography (Condition B). The product was lyophilized affording the title compound as a white solid. MS (ESI): m/z 503 (M+H). HPLC A: 1.88 min.
