실험 절차

1 g of para-toluenesulphonic acid is added to a mixture of 20 mmol of cyclohexanone and 22 mmol of pyrrolidine in 200 ml of dry benzene. The reaction mixture is stirred at reflux until, in the infra-red, the ketone has disappeared, with the enamine concomitantly appearing. The solvent is then evaporated off and the crude residue is purified by distillation in vacuo.
