실험 절차

A solution of Example A3 (3.83 g, 13.79 mmol) in dioxane (50 mL) was sparged with argon, treated with a solution of K2CO3 (3.81 g, 27.6 mmol) in H2O (10 mL), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (3.44 g, 16.55 mmol) and Pd(PPh3)4 (0.637 g, 0.552 mmol) and heated at 80° C. for 16 h. The mixture was cooled to RT, treated with H2O, extracted with EtOAc (2×) and the combined organics washed with H2O, then brine, dried over Na2SO4 and concentrated to dryness. The material was suspended in 3:2 EtOAc/Hex, sonicated and the resulting solid collected via filtration and dried. The filtrate was concentrated to dryness, purified via silica gel chromatography (MeOH/DCM) and combined with the isolated solid to afford N-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)acetamide (3.88 g, 87%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 10.60 (s, 1 H), 8.34 (d, J=5.7 Hz, 1 H), 8.25 (s, 1 H), 8.01 (d, J=8.8 Hz, 1 H), 7.95 (s, 1 H), 7.57 (d, J=8.8 Hz, 1 H), 7.17 (d, J=2.4 Hz, 1 H), 6.58 (dd, J=5.7, 2.4 Hz, 1 H), 3.84 (s, 3 H), 2.25 (s, 3 H), 2.08 (s, 3 H); MS (ESI) m/z: 324.1 (M+H+).
