Reaktionsschritte

6-Fluoro-3-pyridinecarboxaldehyde (152 mg, 1.22=01) was dissolved in tetrahydrofuran (3.0 mL). To this, pyrrolidine (507 μL, 6.08 mmol) was added under a nitrogen atmosphere at room temperature and the mixture was stirred at the same temperature for 2 hours and successively at 60° C. for 5 hours. The reaction mixture was concentrated, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/1) to give 6-(pyrrolidin-1-yl)-3-pyridinecarboxaldehyde (181 mg, yield: 84%).
