How is L-Lysine, N2,N2-bis(carboxymethyl)-, 2,2,2-trifluoroacetate (1:1) (CAS: 160369-83-5) typically synthesized?

L-Lysine, N2,N2-bis(carboxymethyl)-, 2,2,2-trifluoroacetate (1:1) is typically synthesized by the reaction of L-Lysine with trifluoroacetic anhydride and dimethyl carbonate in the presence of a catalyst. This process involves the formation of a trifluoroacetate ester, followed by the introduction of carboxymethyl groups. The synthesis yields a high purity product with good selectivity and yield, making it suitable for various applications in pharmaceutical and biochemical industries.
