실험 절차

To a solution of 2-bromo-6-fluoropyridine (619 mg, 3.52 mmol) in DMSO (3 mL) was added (4-methyltetrahydro-2H-pyran-4-yl)methanamine (500 mg, 3.87 mmol) and triethylamine (498 mg, 4.93 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 [SiO2, 24 g, EtOAc/heptane= 0/100 2 min, 0/100 to 40/60 2-25 min] providing 6-bromo-N-((4-methyltetrahydro-2H-pyran-4-yl)methyl)pyridin-2-amine as a white solid. Yield: 750 mg. LCMS (m/z): 285.0/287.0 [M+H]+; Retention time=0.88 min.
