A method of preparing a N-acyI-N,N',N'-alkylenediamine trialkanoic acid ester comprising contacting a cyclic amidine with an ester of a haloalkanoic acid is provided. In some embodiments, the method involves preparing a N- acyl-N,N',N'-ethylenediamine trialkanoic acid ester by contacting a 2-alkyl imidazoline with the ester of haloalkanoic acid. In some embodiments, the N- acyl-N,N',N'-alkylenediamine trialkanoic acid ester is a synthetic intermediate in the preparation of a N-acyl-N,N',N'-alkylenediamine trialkanoic acid or a salt thereof. In some embodiments, the method provides novel N-acyl-N,N',N'- alkylenediamine trialkanoic acids and/or esters, which can be used, for example, as chelating agents.
