Reaction Steps

A mixture of 5-(5-((2-chloropyridin-4-yl)oxy)pyridin-2-yl)-N-ethyl-4-methoxypyrimidin-2-amine (0.090 g, 0.25 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.060 g, 0.28 mmol), and K2CO3 (0.10 g, 0.76 mmol) in 5:1 dioxane/water (6 mL) was sparged with Ar, treated with Pd(PPh3)4 (0.03 g, 0.025 mmol), sparged again with Ar and heated at 90° C. for 7 h. The mixture was cooled to RT, quenched with satd. NaHCO3, extracted with EtOAc (3×) and the combined organics were washed with brine, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to obtain N-ethyl-4-methoxy-5-(5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (80 mg, 79%). MS (ESI) m/z: 404.2 (M+H+).
