Abstract Two alternative approaches for synthesis of esters of N-(2-chloro-5-nitrobenzyl) amino acids have been developed and compared. We have found synthesis of N-(2-chloro- 5-nitrobenzyl) amino acids via alkylation of esters of amino acids in DMF in the presence of Et 3 N and NaI to be more convenient and have higher yields in comparison with reduction of Schiff bases obtained from 2-chloro-5-nitrobenzaldehyde and corresponding esters of ...
