实验步骤: C17BocSar1 : the product C17BocSar1 is obtained by coupling heptadecylamine with BocSar1 in the presence of dicyclohexylcarbodiimide (DCCI). 3.78 g (0.02 mole) of BocSar and 2.06 g (0.01 mole) of DCCI are mixed cold (at 0° C.) in 100 ml of chloroform. A copious precipitate of dicyclohexylurea (DCU) is formed. The mixture is left for 30 minutes at 0° C., with agitation, and 2.55 g (0.01 mole) of heptadecylamine are added. The reaction is left to proceed for 20 hours. The precipitate is filtered off and washed, the filtrate is recovered, the chloroform is evaporated off, the residue is taken up in 50 ml of THF, the mixture is cooled to 0° C. and filtered to remove the maximum amount of dicyclohexylurea, and the precipitate is washed with the minimum amount of cold THF. C17BocSar1 : the product C17BocSar1 is obtained
