実験手順
A solution of 19.5 parts N-t-butoxycarbonylglycine 2,4,5-trichlorophenyl ester and 11.1 parts L-leucine benzyl ester in 200 parts methylene chloride is stirred overnight at room temperature. The solvent is then removed by evaporation under reduced pressure. The crude dipeptide is then subjected to low-pressure column chromatography on silica gel to afford N-t-butoxycarbonylglycyl-L-leucine benzyl ester.
