Starting from 2-chlorobenzyl alcohol and bis (trichloromethyl) carbonate, 2-chlorobenzyl chloroformate was synthesized with dichloroethane as the solvent, then via reaction with N-hydroxysuccinimide,
the important peptide protecting reagent, N-(2-chlorobenzyloxycarbonyloxy)-succinimide was successfully obtained. The optimum reaction conditions of the two steps were found and the total yield reached 50%. The product was confirmed by ~1H NMR.
