반응 단계
A mixture of 2-chloro-3-nitropyridine 1 (793 mg, 5.0 mmol), methylboronic acid (329 mg, 5.5 mmol), Pd(PPh3)4 (578 mg, 0.5 mmol) and K2CO3 (2.073 g, 15.0 mmol) in dioxane (25 mL) was refluxed for 2 days. It was then cooled to room temperature and filtered. The solvent was removed and the residue was isolated by flash chromatography (50% ethyl acetate in hexanes) to provide 623 mg (90%) of 2-methyl-3-nitropyridine 3.
