実験手順

A solution of 9.6 g of ethyl 2-cyanoethyl(diethoxymethyl)phosphinate in 450 ml of ethanol is added to 82 g of an 8% solution of ammonia in ethanol. To this is added 5 ml of Raney Nickel and the resulting mixture is hydrogenated at 1 bar until the theoretical amount of hydrogen has been taken up. The mixture is then filtered, the filtrate is concentrated under reduced pressure and the crude product is distilled to give ethyl 3-aminopropyl(diethoxymethyl)phosphinate, b.p. 150° C./0.01 mbar, 31P=+46.4 ppm (CDCl3).
