To a solution of the title compound of Example 5 Step A (0.06 mmol, 25 mg) 1H-tetraazol-5-ylmethylamine (0.09 mmol, 12 mg), HOBt (0.15 mmol, 23 mg) and EDC (0.18 mmol, 35 mg) in 0.5 mL of DMF was added DIEA (0.3 mmol, 52 μL). The reaction was allowed to proceed overnight at ambient temperature. The mixture was partitioned between EtOAc/brine. The organic phase was concentrated under reduced pressure and the residue was purified by reverse-phase chromatography (Condition A) and lyophilized, affording the title compound as a white solid. MS (ESI): m/z 517 (M+H). HPLC A: 1.94 min.
