Versuchsvorschrift

A solution of 5.7 g of ethyl 3-nitro-2-phenylpropyl(diethoxymethyl)phosphinate in 60 ml of ethanol is added to 50 g of an 8% solution of ammonia in ethanol. To this are added 9 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 and the filtrate is concentrated under reduced pressure to give ethyl 3-amino-2-phenylpropyl(diethoxymethyl)phosphinate as a viscous oil, 31P=+44.4 ppm (CDCl3).
