实验过程
In a 25 mL sealable tube under nitrogen were combined 6-bromo-N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1-(1-methylethyl)-1H-indazole-4-carboxamide (110 mg, 0.24 mmol), N-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyridinyl]acetamide (104 mg, 0.4 mmol) in DME/water (3 mL:1 mL). PdCl2(dppf)-CH2Cl2 (10.76 mg, 0.013 mmol) was added and the resulting mixture was degassed with nitrogen for 10 min. Sodium bicarbonate (66.4 mg, 0.79 mmol) was added, the vessel was sealed, and the insoluble mixture was heated in a microwave at 120° C. for min. Water was added and the solids that precipitated were filtered off. DCM was added to the solids and it was purified by SiO2 chromatography (eluent: gradient 100% DCM to 80:20:2 DCM/MeOH/NH4OH). Fractions were evaporated. EtOAc was added, it was sonicated and the solids that precipitated were filtered, washed with hexanes and dried to afford the title compound (91 mg, 72%) as a light beige solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.54 (s, 1H) 10.65 (s, 1H) 8.84 (d, J=2.27 Hz, 1H) 8.64 (t, J=4.93 Hz, 1H) 8.39 (s, 1H) 8.25-8.30 (m, 1H) 8.15-8.24 (m, 2H) 7.89-7.93 (m, 1H) 5.89 (s, 1H) 5.18 (quin, J=6.63 Hz, 1H) 4.40 (d, J=4.80 Hz, 2H) 2.22 (s, 3H) 2.13 (s, 3H) 2.12 (s, 3H) 1.51 (s, 3H) 1.50 (s, 3H).
