Reaction Steps
3(S)-aminopyrrolidine-1-carboxylic acid tert-butyl ester (0.93 g, 5.0 mmol), 2-(4-chlorobutoxy)pyridine (0.93 g, 5.0 mmol), potassium carbonate (0.83 g, 6.0 mmol) and sodium iodide (0.83 g, 5.5 mmol) were suspended in acetonitrile (20 ml) and heated under reflux for 24 hours. After cooling to room temperature, water (50 ml) was added to the reaction solution and extraction with ethyl acetate (50 ml) was conducted. The organic layer was washed with water twice and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was then purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1). The purified product was concentrated under reduced pressure to thereby obtain 372 mg of oily colorless 3(S)-[4-(pyridin-2-yloxy)butylamino]pyrrolidine-1-carboxylic acid tert-butyl ester.
