Abstract: Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, are described herein. In particular, the present disclosure describes a process for the production of a nitrile intermediate at a high yield and/or purity. This process includes reacting a dinitrile compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce the chelators at a high yield and/or a high purity.
