In a flame dried flask fitted with a nitrogen inlet, magnetic stirrer, and oil bath was dissolved the 2-(3-chloropropyl)-1,3-dioxolane (25.4 g, 169 mmol) in 70 ml of dimethylsulfoxide. Sodium cyanide (9.1 g, 186 mmol) in 100 ml of dimethylsulfoxide was added and the mixture was heated to 80° C. for 18 hours. The reaction was cooled to room temperature then poured onto ice water and stirred for 1 hour. The mixture was extracted thoroughly with diethyl ether, testing the aqueous after each extraction by TLC for the presence of product. The ether was washed with brine, dried over sodium sulfate, and concentrated in vacuo to give a colorless oil. The oil was purified by silica gel chromatography (50/50 ethyl acetate/hexane) to give 19.2 g of product. (80.7%).
