Versuchsvorschrift

13.7 g of para-cyclohexyl-phenylacetonitrile, 21 ml of absolute ethanol, and 7.3 ml of concentrated sulfuric acid are boiled overnight. The mixture is then diluted with water and extracted several times with ethyl acetate. The solution is washed with sodium bicarbonate solution and water, and dried over sodium sulfate. The residue obtained on evaporation of the solvent is distilled in a high vacuum. There is obtained para-cyclohexylphenyl acetic acid ethyl ester boiling at 125°-127°C under a pressure of 0.5 mm of Hg.
