Reaction Steps

A solution of Example C1 (0.12 g, 0.26 mmol) and 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.070 g, 0.35 mmol) in dioxane (4 mL) was sparged with Ar, treated with a solution of K2CO3 (0.07 g, 0.51 mmol) in water (1 mL), Pd(PPh3)4 (0.03 g, 0.026 mmol) and heated at 90° C. for 2 h. The mixture was cooled to RT, diluted with water, extracted with EtOAc (2×) and the combined organics were washed with brine, dried over Na2SO4, concentrated to dryness and purified by column chromatography (MeOH/DCM) to afford N-ethyl-4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine as a white solid (77 mg, 71%). 1H NMR (400 MHz, DMSO-d6): δ 8.74 (s, 1H), 8.36 (d, J=5.7 Hz, 1H), 8.26 (s, 1H), 7.97 (d, J=0.7 Hz, 1H), 7.76 (d, J=8.5 Hz, 1H), 7.55 (d, J=8.6 Hz, 1H), 7.36 (br s, 1H), 7.25 (d, J=2.4 Hz, 1H), 6.61 (dd, J=5.7, 2.4 Hz, 1H), 3.96 (s, 3H), 3.84 (s, 3H), 3.40-3.30 (m, 2H), 2.37 (s, 3H), 1.14 (br m, 3H); MS (ESI) m/z: 418.2 (M+H+).
