The title compound was obtained following procedure described for example 26, but starting from 4-[4-(1H-indazol-3-yl)-1H-1,2,3-triazol-1-yl]benzoic acid (100 mg; 0.33 mmol; 1.0 eq.) and 3-amino-1-methylpyrrolidin-2-one (Chem Bridge Corp., 56 mg, 0.49 mmol, 1.5 eq.). The crude obtained was suspended in acetonitrile, filtered and dried to afford the title compound as a beige powder. 1H NMR (300 Mz, DMSO-d6) δ 13.38 (s, 1H), 9.43 (s, 1H), 8.94 (d, J=8.4 Hz, 1H), 8.36 (d, J=8.1 Hz, 1H), 8.21 (d, J=8.8 Hz, 2H), 8.11 (d, J=8.8 Hz, 2H), 7.61 (d, J=8.4 Hz, 1H), 7.50-7.38 (m, 1H), 7.31-7.15 (m, 1H), 4.74-4.52 (m, 1H), 3.42-3.32 (m, 2H), 2.77 (s, J=7.8 Hz, 3H), 2.44-2.27 (m, 1H), 2.13-1.85 (m, 1H). HPLC (Condition A): Rt 2.69 min (purity 92.2%). MS (ESI+): 402.3, MS (ESI−): 400.3.
