実験手順

A solution of 5-bromo-1-(tetrahydro-2H-pyran-2-yl)-N-(6-(trifluoromethyl)pyridin-3-yl)-1H-indazole-3-carboxamide (CXXVIII) (0.469 g, 1 mmol), 5-fluoro-pyridyl-3-boronic acid (CXXIX) (0.156 g, 1.1 mmol), potassium phosphate tribasic (0.318 g, 1.5 mmol) and water (degassed, 1 mL) in DMF (10 mL) was purged with argon. Tetrakis(triphenylphosphine)palladium(0) (0.034 g, 0.03 mmol) was added and the solution was purged again with argon. The reaction was heated to 90° C. for 3 h when TLC showed disappearance of starting material. The solution was cooled to room temperature and excess solvent was removed under vacuum. The residue was treated with water, sonicated briefly and the solids formed were filtered. The solids were washed with cold water and dried under vacuum at room temperature which was purified by silica gel column chromatography (2:8 EtOAc:hexanes→3:7 EtOAc:hexanes) to afford 5-(5-fluoropyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-N-(6-(trifluoromethyl)pyridin-3-yl)-1H-indazole-3-carboxamide (CXXX) as a white solid (427 mg, 0.88 mmol, 88% yield). 1H NMR (DMSO-d6) δ ppm 10.95 (s, 1H), 9.25 (d, J=1.8 Hz, 1H), 8.85 (m, 1H), 8.63 (d, J=1.8 Hz, 1H), 8.61 (d, J=2.1 Hz, 1H), 8.53 (m, 1H), 8.16-8.13 (m, 1H), 8.08 (d, J=7.1 Hz, 1H), 7.97-7.94 (m, 2H), 6.11 (dd, J=8.1, 1.8 Hz, 1H), 4.01 (m, 1H), 3.88-3.83 (m, 1H), 2.63-2.60 (m, 1H), 2.11-2.07 (m, 2H), 1.83-1.80 (m, 1H). 1.69-1.65 (m, 2H); ESIMS found for C24H19F4N5O2 m/z 486.0 (M+H).
