Procedure

Formic acid (2.0 ml.) was added dropwise to acetic anhydride (2.45 g.) at ambient temperature with stirring. After the stirring was continued at the same temperature for 30 minutes, 3-(N-hydroxyamino)propylphosphonic acid (3.10 g.) was added to the mixture. The reaction mixture was stirred for an hour and concentrated under reduced pressure to give a residue, which was dissolved in water (25 ml.) To the aqueous solution was added ethylenediamine (0.60 g.). The mixture was concentrated under reduced pressure to give a residue, which was dissolved in water. The aqueous solution was concentrated under reduced pressure to give a residue, and to the residue was added ethanol (30 ml.) to give crystals. The crystals were separated by filtration and washed twice with ethanol (10 ml.) to give crystalline ethylendiamine bis[3-(N-formyl-N-hydroxyamino)propylphosphonate] (3.95 g.), a part (3 g.) of which was recrystallized from 90% aqueous methanol to give needles (1 g.) of the same object compound.
