Versuchsvorschrift

A solution of 1.3 g (8.27 mmol) of 4-formyl-3-vinylbenzonitrile in 35 ml of ethanol is mixed with 880 mg of 10% palladium on carbon and vigorously stirred under a hydrogen atmosphere for 2 h. The suspension is filtered through a layer of kieselguhr, the residue is washed with ethanol, and the filtrate is concentrated. The residue (890 mg) is employed without further purification in the following stage.
