Reaktionsschritte

To 20 millimoles (2.66 g) of phenoxyacetonitrile in 6 ml of anhydrous ether, is added a solution of 30 millimoles (1.5 eg) of benzylmagnesium bromide in 6 ml of anhydrous ether. The mixture sets to a mass and 10 ml of tetrahydrofuran are added. After stirring for 2 hours at room temperature, the reaction mixture is cooled by an ice-bath, then added with 50 ml of a normal solution of sodium cyanide in dimethylformamide. After 2 hours of stirring at room temperature, the mixture is hydrolyzed by 10 ml of methanol then by pasty sodium sulfate. There are obtained 3.45 g of raw product, which purified by high pressure liquid chromatography on silica, with a solution by ethyl acetate/petroleum ether 1/1, give 0.3 g of 2-amino-2-benzyl-3-phenoxy-propionitrile. Yield: 6.3%
