A solution of Example C3 (0.12 g, 0.28 mmol) in dioxane (4 mL) was sparged with Ar, treated with 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.08 g, 0.42 mmol), a solution of K2CO3 (0.077 g, 0.55 mmol) in water (1 mL) and Pd(PPh3)4 (0.032 g, 0.03 mmol) and heated at 90° C. overnight. 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 via silica gel chromatography (MeOH/DCM) to afford N-(5-((2-(1H-pyrazol-4-yl)pyridin-4-yl)oxy)-6-methylpyridin-2-yl)-2-oxo-3-(tetrahydro-2H-pyran-4-yl)imidazolidine-1-carboxamide (72 mg, 56%). 1H NMR (400 MHz, DMSO-d6): δ 13.05 (br s, 1 H), 10.89 (s, 1 H), 8.35 (d, J=5.7 Hz, 1 H), 8.31 (brs, 1 H), 8.03 (s, 1 H), 7.89 (d, J=8.8 Hz, 1 H), 7.61 (d, J=8.8 Hz, 1 H), 7.28 (d, J=2.4 Hz, 1 H), 6.56 (dd, J=5.7, 2.4 Hz, 1 H), 3.95-3.77 (m, 5 H), 3.43-3.39 (m, 4 H), 2.24 (s, 3 H), 1.71-1.70 (m, 2 H), 1.60 (d, J=12.4 Hz, 2 H); MS (ESI) m/z: 464.2 (M+H+).
