Abstract:
The invention relates to a method for preparing an activated ester of the formula (I), where R is a (C1-C6) alkyl, aryl, heteroaryl, cycloalkyl, or heterocycloalkyl group, and ALK is a (C1-C6) alkylene group, said method consisting of reacting the dicyclohexylamine P1 salt and the disuccinimidyl carbonate (DSC) in a solvent in which the dicyclohexylamine salt of the N-hydroxysuccinimide P2 is precipitated. The invention also relates to products of the formula P1.
