27.6 g of tosylmethyl isocyanide and 17 g of 2-pentylcyclopentanone were dissolved in 400 ml of 1,2-dimethoxyethane and 10 ml of ethanol. The solution was cooled to 0° C. with an ice-bath, and 29 g of tBuOK were added in 1 hour maintaining the temperature between 0 and 10° C. After completion of the reaction, the reaction mixture was poured into water and extracted with cyclohexane. The organic layer was washed 3 times with water until neutral pH. Purification by bulb-to-bulb distillation (130° C./0.06 mbar) gave 10.7 g of the pure 2-pentylcyclopentanecarbonitrile.
