Versuchsvorschrift

Cyclohexanone (196.3 g) and pyrrolidine (214 g) in benzene (500 ml) were refluxed under nitrogen with a Dean-Stark apparatus, until no more water separated out. The solvents were then evaporated off under nitrogen, and the residual oil was distilled to give 1-(1-pyrrolidinyl)cyclohexene (290 g).
