A new selective method has been proposed for the preparation of glycopeptides of β-glycyrrhizic acid (I) containing fragments of methyl esters of amino acids by reacting tris-N-hydroxysuccinimidic ester of a glycoside, obtained in situ using N,N'-dicyclohexylcarbodiimide, with hydrochlorides of methyl esters of amino acids or dipeptides in the presence of triethylamine.
