PROCEDURE

实验过程

To a solution of 6.0 g (S)-2-Benzyloxycarbonylamino-pentanedioic acid 5-tert-butyl ester in 50 ml DMF were added 3.3 g piperazine-1-carboxylic acid cyclobutyl ester, 9.1 ml N-ethylmorpholine and 5.9 g TOTU. After stirring for 12 h the solution was diluted with ethyl acetate and subsequently washed with aqueous LiCl (4%) and saturated aqueous NaHCO3. The crude product obtained after evaporation of the solvent was used without further purification. Yield: 11.1 g.
