Versuchsvorschrift

527 g of 4-isobutylbenzyl chloride, 153 g of sodium cyanide and 720 ml of dimethylsulfoxide are agitated for 6 hours at 40° C. The mixture is cooled and then diluted with water. An oily layer separates and is extracted with ether. The ether solution is subjected to fractionation and yields 367 g of 4-isobutylphenyl acetonitrile.
