Summary:Reaction pathways and conditions for the production of nitrogen-containing chelators, such as a glycine derivative, with reduction of ammonia byproducts. In particular, the present disclosure describes a process for the production of a nitrile intermediate by reacting a tetra-amino compound or dinitrile compound with an aldehyde and a hydrogen cyanide to form the nitrile intermediate. The nitrile intermediate may then be further processed to produce chelators at a high yield and/or a high purity.
