Reaction Conditions

Reaction Steps

To a solution of 0.25 millimoles of N,N'-bis(dihydroxyphosphorylmethyl)-1,4,7-triazacyclononane in water were added 0.3 millimoles of chloroacetic acid, and the pH was adjusted to 9.0 by dropwise, addition of NaOH. The mixture was then heated to 80° C. and held at that temperature overnight. Hydrochloric acid was then added to a pH of 1.5, and the water was evaporated. The solids were then triturated with ether followed by ethanol to remove contaminants, and the remaining solid product was identified by proton NMR as N-carboxymethyl-N',N"-bis(dihydroxyphosphorylmethyl)-1,4,7-triazacyclononane.
