Reaction Steps

4-Nitro-2-(pyrrolidin-1-yl)pyridine (560 mg, 2.90 mmol) was dissolved in methanol (21 mL) and methylene chloride (8.3 mL) and the solution was added with palladium carbon (50% aqueous, 560 mg), followed by stirring at room temperature for 1 hour under hydrogen atmosphere. After filtering off the insoluble matter of the reaction mixture, the solvent was evaporated under reduced pressure to obtain 2-(pyrrolidin-1-yl)pyridin-4-ylamine (474 mg, 91%).
