To a solution of the title compound of Example 223 Step C (0.16 mmol, 68 mg), 1H-tetraazol-5-amine monohydrate (0.48 mmol, 49 mg), HOBt (0.32 mmol, 49 mg) and EDC (0.32 mmol, 61 mg) in 1 mL of DMF was added DIEA (0.48 mmol, 83 μL). The reaction mixture was warmed to 40° C. for 2 h, then concentrated under reduced pressure. The residue was purified by reverse-phase chromatography (Condition B). The product was lyophilized, affording a white solid. 1H NMR (500 MHz, d6-DMSO) δ 12.38 (s, 1H), 8.07 (d, 2H), 7.73 (d, 2H), 7.63 (m, 1H), 7.56 (m, 1H), 7.24-7.33 (overlapping m, 2H), 7.15 (t, 1H), 6.90 (d, 2H), 5.31 (s, 2H), 3.53 (s, 3H). MS (ESI): m/z 493 (M+H). HPLC A: 1.69 min.
