Aminoalkylphosphonic acids are prepared via amino group protection by nitrogen-phosphorus (P-N) bond formation. Phosphorylation of β or γ-bromoalkylamines with chlorophosphates followed by reaction of the resulting haloalkylphosphoramidates with triethylphosphite (Arbuzov reaction) to give a phosphoramidate-phos-phonate intermediate which can be alkylated with various reagents. Removal of the phosphoryl
