Versuchsvorschrift

A solution of N-benzyl piperidone (20.0 g, 53 mmol) and pyrrolidine (14.0 mL, 80 mmol) in 300 mL of toluene was warmed at reflux overnight with azeotropic removal of water. The reaction mixture was then cooled and concentrated under reduced pressure. The resultant dark oil was dissolved in 200 mL of ether, dried over magnesium sulfate, filtered and concentrated under reduced pressure.
