 Composition for magnetic resonance imaging - Patent 5138040
If an acid chloride is used as a starting material, then the reaction solvent advantageously is one which does not contain reactive functional groups, such as hydroxyl groups, as these solvents can react with the acid chlorides, thus producing unwanted byproducts.
Following the reaction of the reactive derivative with the amine, any remaining anhydride or acid chloride groups can be hydrolyzed to the carboxylic groups by adding a stoichiometric excess of water to the reaction mixture and heating for a short time.
