26.9 g (100 mmol) of (1-cyanocyclohexyl)malonic acid dimethyl ester, 4.3 g (100 mmol) or lithium chloride and 3.6 g (200 mmol) of water were heated in 300 ml of dimethyl sulfoxide for 22 hours to 150° C. Then it was cooled mixed with 700 ml of water and extracted with 1000 ml of pentane. 14.4 g of (1-cyanocyclohexyl)acetic acid ethyl ester was obtained by distillation of the organic phase, corresponding to a yield of 74 percent (relative to the (1-cyanocyclohexyl)malonic acid dimethyl ester used). Data for the product was:
