Procedure

To a suspension of 11.3 g (0.23 mole) of sodium cyanide in 100 ml of dry dimethyl formamide (DMF) is added dropwise a solution of 50 g (0.154 mole) of 2-(2,4-dichlorophenyl)-hexylmethane sulfonate in 50 ml of DMF. The reaction mixture is stirred at 70° overnight. It is then poured into 500 ml of water and extracted with ether. The combined ether extracts are washed with water, then saturated saline solution and finally dried over magnesium sulfate. Solvent is evaporated under reduced pressure to give 37 g of crude product which is further purified by vacuum distillation (107.5°-110°/0.05 mm) to give 33.9 g (86%) of expected product.
