実験手順
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-dimethylamino pyrrolidine (56 mg, 0.49, 1.5 eq.). Purification by flash chomatography on silica (DCM:MeOH:NH4OH, gradient from 100:0:0 to 90:10:0.1) afforded the title compound as a yellow powder. 1H NMR (300 Mz, DMSO-d6) δ 13.37 (s, 1H), 9.39 (s, 1H), 8.36 (d, J=8.2 Hz, 1H), 8.13 (d, J=8.3 Hz, 2H), 7.83-7.72 (m, 2H), 7.61 (d, J=8.4 Hz, 1H), 7.53-7.36 (m, 1H), 7.33-7.19 (m, 1H), 3.77-3.18 (m, 5H), 2.78-2.60 (m, 1H), 2.24-1.92 (m, 6H), 1.82-1.69 (m, 1H). HPLC (Condition A): Rt 2.20 min (purity 90.1%). MS (ESI+): 402.3, MS (ESI−): 400.3.
