Reaction Steps

Following isolation, the formula (LXXXV) quinoline-2,3-dicarboxylic acid is heated to about 70° C. to 95° C. with an excess of acetic anhydride to yield the formula (LXXXVI) 2,3-quinolinedicarboxylic acid anhydride. A co-solvent such as pyridine or pyridinedimethoxyethane may also be used in this reaction, but is not essential to obtain the desired product.
