Reaction Steps
A mixture of 6-difluoromethoxyquinoline-2,3-dicarboxylic acid (0.14 mol) in 125 mL acetic anhydride is heated at 85° C. for one-half hour and then at 100° C. for one hour. The mixture is cooled, then filtered and the solids washed with ether to give 6-difluoromethoxyquinoline-2,3-dicarboxylic acid anhydride mp 157.5°-158.5° C.
