90 g of di-(ethyloxy)ethyl-cyclohexane-carbonitrile are dissolved in 1 l of ethanol, and 60 g of sodium are added. After dissolution of the metal, 100 ml of water are added, and the solvent is substantially removed in vacuo. 300 ml of water are added to the residue, and it is extracted three times with 200 ml of ether. The ethereal phase is dried over sodium sulfate, concentrated, and distilled in vacuo.
