Versuchsvorschrift

To a solution of N-benzylpyrrolidinone (2.18 g, 12.4 mmol) in 25 mL of ether was added at 0° C. triethyloxonium tetrafluoroborate (2.15 g, 11.3 mmol). The reaction was allowed to warm to ambient temperature and stir for 30 minutes, during which a solid product precipitated from the reaction. The ether was decanted off, and the remaining residue washed three times with ether. Residual solvent was removed in vacuo to provide 1-benzyl-5-ethoxy-3,4-dihydro-2H-pyrrolium tetrafluoroborate.
