Reaction Conditions

Reaction Steps

2-Chloro-4-nitropyridine (2.0 g, 12.2 mmol) was dissolved in THF (30 mL) and the solution was added with pyrrolidine (3.25 mL, 38.9 mmol), followed by stirring at 80° C. overnight. After an insoluble matter of the reaction mixture was filtered off, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=20/80) to obtain 4-nitro-2-(pyrrolidin-1-yl)pyridine (560 mg, 24%).
