18.6 g of sodium cyanide in 222 ml of dimethyl sulphoxide are treated at 50° C with 74 g of 3-fluoro-6-(phenylthio)-benzyl chloride in 75 ml of dimethyl sulphoxide in one portion. The resulting dark solution is stirred at 45°-50° C for 1 hour, subsequently poured on to 1500 ml of ice-water and extracted with ether. The organic phase is washed three times with 500 ml of water each time, dried over sodium sulphate and evaporated. There is obtained 3-fluoro-6-(phenylthio)-phenylacetonitrile as a reddish oil.
