To a solution of 2-bromo-6-fluoropyridine (3 g, 17.05 mmol) in DMSO (8 mL) was added (tetrahydro-2H-pyran-4-yl)methanamine (3.10 g, 20.46 mmol) and triethylamine (5.68 mL, 40.9 mmol). The mixture was heated at 110° C. for 18 hr. The mixture was allowed to cool to ambient temperature and diluted with EtOAc. The organic layer was washed with saturated aqueous NaHCO3 solution (1×), water (1×), brine (1×), dried over Na2SO4, filtered off and concentrated in vacuo. The resulting residue was purified by column chromatography over silica gel providing 6-bromo-N-((tetrahydro-2H-pyran-4-yl)methyl)pyridin-2-amine as a white solid. Yield: 4.24 g. LCMS (m/z): 270.9/273.0 [M+H]+; Retention time=0.78 min.
