Procedure

A mixture of 6.83 g of ethyl 3-aminopropyl(phenyl)phosphinate and 30 ml of 20% hydrochloric acid is refluxed with stirring for 4 hours. The clear solution is evaporated to dryness and the residue is recrystallized from methanol/propylenoxide to give 3-aminopropyl(phenyl)phosphinic acid as a white solid, m.p. 298°-300°.
