Reaction Conditions

Reaction Steps

A mixture of 2,3,6-trifluoropyridine (858 mg, 6.45 mmol), (4-methyltetrahydro-2H-pyran-4-yl)methanamine (1000 mg, 7.74 mmol) and triethylamine (2.158 mL, 15.48 mmol) in NMP (16 mL) was heated at 70° C. for 1 hr. The reaction mixture was allowed to ambient temperature and was diluted with EtOAc (˜100 mL), brine (˜50 mL) and water (˜50 mL). The separated organic layer was washed with brine (1×), 0.3N aqueous HCl (2×), saturated aqueous NaHCO3 solution (1×), brine (1×), dried over Na2SO4, filtered off and concentrated in vacuo to provide crude 3,6-difluoro-N-((4-methyltetrahydro-2H-pyran-4-yl)methyl)pyridin-2-amine as a colorless oil, which was directly used in the next reaction without further purification. Yield: 1.4 g. LCMS (m/z): 243.1 [M+H]+; Retention time=0.86 min.
