After the obtaining of the N-protected methyl α,α-diamino ester via N-alkylation reaction between methyl α-bromo glycinate N-benzoylated and 2-methyl quinolin-4-amine, the synthesis of benzoylamino-(2-methyl-quinolin-4-ylamino) acetic acid in high yield through alkaline hydrolysis reaction of methyl 2-benzamido-2-(2-methylquinolin-4-ylamino) acetate was performed via cleavage of the protecting group. The structure of these products were established on the basis of NMR spectroscopy (¹H, ¹³C), and MS data.
Keywords: N-alkylation, α,α-Diamino ester, α,α-diamino acid, methyl α-bromo glycinate, alkaline hydrolysis reaction.
