Versuchsvorschrift

1.13 g of (2-nitro-benzyl)-phosphonic acid diethyl ester) in ethanol are hydrogenated with Pd—C as a catalyst for 5 hours at rt and ambient pressure. The catalyst is removed by filtration and from the filtrate obtained solvent is evaporated. (2-Amino-benzyl)-phosphonic acid diethyl ester is obtained.
