AbstractA process for the synthesis of N6-trifluoroacetyl-L-lysine has been studied. Ethyl trifluoroacetateformed from the reaction of ethanol and trifluoroacetic acidreacted with L-lysine to afford the title compound in 91.8% yield with purity of 95.5%HPLC. Best results of acylation were obtained at -5~5pH value 11~13 and reaction time of 2 h. |
Key wordsN6-trifluoroacetyl-L-lysinetrifluoroacetic acidL-lysineacylation |
