Reaction Steps

3-Methyl-5-(pyridin-3-yl)aniline (50.7 mg, 0.275 mmol) was added a solution of tert-Butyl 4-[(2-chloropyrimidin-4-yl)oxy]piperidine-1-carboxylate (72.0 mg, 0.229 mmol) in dioxane (486 μL). The reaction mixture was flushed and purged with Ar(g) followed by the addition of Pd(OAc)2 (5.15 mg, 0.023 mmol) and Xantphos (19.9 mg, 0.034 mmol). The reaction was heated to 75° C. overnight and then cooled to room temperature. The reaction mixture was diluted with water and extracted with dichloromethane. The organic was dried over sodium sulfate and was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (10% MeOH in DCM:hexanes, 10:90 to 50:50) to yield tert-butyl 4-[(2-{[3-methyl-5-(pyridin-3-yl)phenyl]amino}pyrimidin-4-yl)oxy]piperidine-1-carboxylate.
