Process for preparing substituted polyazamacrocycles |
| abstract |
A process for preparing a substituted polyazamacrocycle is provided which comprises contacting a diamine or triamine and a dicarboxylic acid or ester or anhydride thereof in the presence of a suitable base and a suitable solvent to produce the substituted polyazamacrocycle provided that when an ester of said dicarboxylic acid is used, said suitable base is optional, and when said dicarboxylic acid or an anhydride of said dicarboxylic acid is used, the reaction mixture further comprises a suitable coupling agent. |
