Reaction Steps

58.8 g (1.2 mol) of sodium cyanide and 22.28 g (0.12 mol) of benzyltrimethylammonium chloride are dissolved in 360 ml of water. Thereafter 181.03 g (1.0 mol) of 2-[1,3]-dioxolan-2-yl-1-bromoethane are added dropwise and the reaction mixture is heated at 90° C. After six hours it is cooled, diluted with 400 ml of water and subjected to extraction with ether. Drying over magnesium sulfate and evaporation of the solvent give 111.85 g of 3-[1,3]-dioxolan-2-yl-propionitrile as a reddish oil which is used without further purification in the next stage of the reaction.
