Conditions

Temperature
95 °C

Procedure

209 g of 2,2-dicyclopropylethanol tosylate (prepared from 2,2-dicyclopropylethanol and para-toluenesulfonyl chloride) in solution in 45 ml of DMSO, are slowly added to 40 g of sodium cyanide in 45 ml of dimethyl sulfoxide (DMSO), with stirring and at 95° C. The heating is continued for one hour. After filtration of the precipitate and washing with ethyl ether, the filtrates are pooled, washed with a saturated solution of sodium chloride, dried and evaporated. The expected product is obtained after distillation under vacuum.
