Reaction Steps

To a solution of 2-azetidin-3-yl-quinoline hydrochloride (1.70 g, 7.75 mmol) in DMF (30 mL) at room temperature was added Cs2CO3 (5.2 g, 16 mmol) and 2,3-dichloro-pyrazine (1.3 g, 9.0 mmol). The reaction mixture was heated to 90° C. overnight and then diluted with water (60 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were washed with water (60 mL) and brine (60 mL), dried over Na2SO4, and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography on silica gel (5% to 30% EtOAc in hexanes) to give the title product (1.30 g, 4.4 mmol, 58% yield) as a white solid.
