Versuchsvorschrift

5.2 g (35 mmol) of 4-formylbenzoic acid was dissolved in 100 ml of dichloromethane. 2.0 g (29 mmol) of pyrroline, 5.9 g (35 mmol) of 2-chloro-1,3-dimethylimidazonium chloride and 6.1 ml (43 mmol) of triethylamine were added to the obtained solution, and they were stirred at room temperature for 5 hours. After the treatment with dichloromethane as the extracting solvent by an ordinary method, the crude product was obtained.
