Reaction Steps

A mixture of 2-bromo-6-fluoropyridine (750 mg, 4.26 mmol) in DMSO (3 mL) was mixed with (tetrahydro-2H-pyran-4-yl)methanamine hydrochloride (775 mg, 5.11 mmol) and NEt3 (1.426 mL, 10.23 mmol). The resulting mixture was heated at about 110° C. for 18 hr. The mixture was cooled to ambient temperature and diluted with EtOAc. The organic layer was separated, washed with saturated aqueous sodium bicarbonate solution, water, and brine, dried over sodium sulfate, filtered and concentrated in vacuo to yield a resulting residue. The resulting residue was purified by column chromatography [SiO2, 40 g, EtOAc/heptane=0/100 to 30/70]. Pure fractions were combined and concentrated in vacuo providing 6-bromo-N-((tetrahydro-2H-pyran-4-yl)methyl)pyridin-2-amine (B1, 940 mg) as a white solid. LCMS (m/z): 271.0/272.9 [M+H]+; Retention time=0.81 min.
