PROCEDURE

实验过程

To a solution of 1.61 g (S)-2-tert-Butoxycarbonylamino-5-(tert-butyl-diphenyl-silanyloxy)-pentanoic acid in 8 ml DMF were added 1.02 g piperazine-1-carboxylic acid butyl ester hydrotrifluoroacetate, 1.7 ml N-ethylmorpholine and 1.1 g TOTU. After stirring for 12 h the solution was diluted with ethyl acetate and subsequently washed with aqueous LiCl (4%), 0.1 M HCl and saturated aqueous NaHCO3. The crude product obtained after evaporation of the solvent was used without further purification. Yield: 1.80 g.
