The title compound was prepared in the same manner as described for example 35 (step b) from methyl 1-isopropyl-6-(1H-pyrrolo[2,3-b]pyridin-5-yl)-1H-indazole-4-carboxylate 1 (0.6 g, 1.79 mmol) and LiOH.H2O (0.22 g, 5.37 mmol) wherein the mixture was heated at 80° C. for 5 h. The product was collected as an off-white solid (0.5 g, 87.7%). 1H NMR (DMSO-d6, 400 MHz): δ 1.530 (d, J=6.4 Hz, 6H), 5.199-5.265 (m, 1H), 6.552 (d, J=1.6 Hz, 1H), 7.550 (t, J=2.4 Hz, 1H), 8.11 (s, 1H), 8.328 (s, 1H), 8.383 (d, J=1.6 Hz, 1H), 8.401 (s, 1H), 8.671 (d, J=1.6 Hz, 1H), 11.77 (brs, 1H). LCMS (ES+) m/z: 321.24.
