Treatment of bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (I) with acetic anhydride in hot pyridine produced the cyclic anhydride (II). Ethyleneglycol mono-ether (V) was prepared by Williamson's synthesis from the sodium alkoxide of ethylene glycol (IV) and octadecyl bromide (III). Then, heating the bis-anhydride (II) with ethyleneglycol monoether (V) produced the title diester
