반응 단계

In a schlenck tube, a mixture of 2,5-dibromopyridine (2.11 mmol, 0.500 g), 3-fluoro-4-(tributylstannyl)pyridine (2.32 mmol, 0.896 g), PdCl2(PPh3)2 (0.21 mmol, 0.148 g), CuI (0.43 mmol, 0.080 g) in DMF (5 ml) was heated at 130° C. for 12 hours, under argon atmosphere. The solvent was evaporated and the crude mixture was extracted between water and ethyl acetate. The solid residue was purified by chromatography over SiO2 eluting with DCM/methanol mixtures affording 0.330 g (yield 62%) of the expected product.
