ABSTRACT:
Methods to prepare intermediates for the conjugation of active ingredients to hydrophilic carriers are described. The polyhydroxylated carriers are first derivatized to convert the hydroxyls to leaving groups and then reacted with an alkylene diamine in the presence of a reducing agent. The resulting derivatized carrier can then be coupled to substituents containing carboxyl groups in the presence of dehydrating agents.
