Reaction Steps

A solution of Example A9 (0.440 g, 1.985 mmol) in dioxane (8 mL) was sparged with Ar, treated with a solution of K2CO3 (0.549 g, 3.97 mmol) in water (2 mL) and 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.565 g, 2.58 mmol), sparged again with Ar, treated with Pd(PPh3)4 (0.229 g, 0.199 mmol) and heated at 80° C. overnight. The mixture was cooled to RT, diluted with EtOAc, the solids removed via filtration through diatomaceous earth and the filtrate concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford 5-((2′-methyl-[2,4′-bipyridin]-4-yl)oxy)pyridin-2-amine (490 mg, 89%) as a light brown solid. MS (ESI) m/z: 279.2 (M+H+).
