Dicyclohexylcarbodiimide → succinimidyl N-(cholest5-en-3beta-oxycarbonyl)glycinate

Participants

Reaction Steps

To a solution of N-(cholest-5-en-3β-oxycarbonyl)glycine (2.92 g) in a mixture of dioxane (40 ml) and chloroform (6 ml) were added successively N-hydroxysuccinimide (0.69 g) and dicyclohexylcarbodiimide (1.236 g) at 0° C. and the reaction mixture was stood for 16 hours in a refrigerator. The resulting precipitate was collected by filtration and the filtrate was concentrated in vacuo to give succinimidyl N-(cholest5-en-3β-oxycarbonyl)glycinate (3.23 g).
