Reaction Steps

Triethylamine (560 mg, 5.6 mmol), 1-(quinolin-2-yl)azetidin-3-amine hydrochloride (557 mg, 2.8 mmol) and 2,3-dichloro-pyrazine (414 mg, 2.8 mmol) were dissolved in DMF (20 mL). The resulting mixture was heated to 90° C. overnight. The mixture was then diluted with water (20 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were combined and washed with water (20 mL) and brine (20 mL), dried over Na2SO4, and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography on silica gel (20% to 50% EtOAc in petroleum ether) to give 3-chloro-N-(1-(quinolin-2-yl)azetidin-3-yl)pyrazin-2-amine (479 mg, 1.5 mmol, 55% yield) as white solid. ESI-MS (M+1): 312 calc. for C16H14ClN5 311.
