Reaction Steps

A mixture of 5-(5-((2-chloropyridin-4-yl)oxy)-6-methylpyridin-2-yl)-3-methyl-2-(methylthio)pyrimidin-4(3H)-one (0.52 g, 0.97 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.22 g, 1.07 mmol), and K2CO3 (0.40 g, 2.9 mmol) in 5:1 dioxane/water (6 mL) was sparged with Ar, treated with Pd(PPh3)4 (0.12 g, 0.10 mmol), sparged again with Ar and heated at 90° C. overnight. The solids were removed via filtration, the filtrate treated with satd. NaHCO3, extracted with EtOAc (3×) and the combined organics were dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford 3-methyl-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(methylthio)pyrimidin-4(3H)-one (140 mg, 34%). MS (ESI) m/z: 421.1 (M+H+).
