Reaction Steps

A mixture of 4.67 g (0.015 mol) of diethyl phthalimidoethylphosphonate in 30 ml. of ethanol and 1.2 ml of 100% hydrazine hydrate is kept at ambient temperature for ca. 16 hours then is refluxed for 2 hours. The mixture is cooled and filtered and the filtrate is concentrated to give diethyl (2-aminoethyl)phosphonate.
