A glass microwave reaction vessel was charged with 4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)aniline (0.167 g, 0.619 mmol), 2-bromo-5-methylpyridine (0.0888 g, 0.516 mmol), BrettPHOS precatalyst (8.26 mg, 10.32 μmol), and sodium tert-butoxide (0.124 g, 1.291 mmol). The flask was placed under vacuum then flushed with argon. Dioxane (1.7 mL) was added and the reaction was heated to 90° C. to stir overnight. After cooling to room temperature, the reaction mixture was concentrated and the crude product was adsorbed onto a plug of silica gel and chromatographed through a Biotage pre-packed silica gel column (40S), eluting with a gradient of 10% to 100% EtOAc in hexane, to provide 5-methyl-N-(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)pyridin-2-amine. MS (ESI, pos. ion) m/z: 362.1 (M+1). IC50 (uM) 0.002387.
