HCID 67467381Methyl 1-isopropyl-3-methyl-6-(1H-pyrrolo[2,3-b]pyridin-5-yl)-1H-indazole-4-carboxylate

Procedure

The title compound was prepared from methyl 6-bromo-1-isopropyl-3-methyl-1H-indazole-4-carboxylate, (0.7 g, 2.25 mmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (0.65 g, 2.70 mmol) in the same manner as described for example 80 (step a). The product was collected as an off-white solid (600 mg, 82.5%). 1H NMR (DMSO-d6, 400 MHz): 1.489 (d, J=6.4 Hz, 6H), 2.603 (s, 3H), 3.949 (s, 3H), 5.140-5.172 (m, 1H), 6.547 (s, 1H), 7.545 (s, 1H), 7.935 (s, 1H), 8.253 (s, 1H), 8.377 (s, 1H), 8.667 (s, 1H), 11.774 (s, 1H). LCMS (ES+) m/z: 349.
