Toluene → 1-(4-Propylcyclohex-1-enyl)pyrrolidine

Participants

Reaction Steps

Toluene (200 ml) and pyrrolidine (90 ml) were added to 4-propylcyclohexanone (53.0 g) in a reaction vessel equipped with a Dean-Stark apparatus under an atmosphere of nitrogen. The mixture was refluxed for 3 hours while the water formed was removed by a Dean-Stark apparatus. After the reaction mixture had been cooled to a room temperature, it was washed with brine, and dried over anhydrous magnesium sulfate. The toluene was distilled off under reduced pressure to give 1-(4-propylcyclohex-1-enyl)pyrrolidine (58.2 g).
