Reaction Steps
To a solution containing dimethyl 6-difluoromethoxyquinoline-2,3-dicarboxylate (0.162 mol) in 150 mL ethanol is added a solution of sodium hydroxide (0.5 mol) in 400 mL water and the mixture heated at reflux for five hours. The ethanol is removed in vacuo. The residue cooled to 5° C. and acidified with concentrated HCl. The product is removed by filtration, washed with water and dried to give 6-difluoromethoxyquinoline-2,3-dicarboxylic acid mp 226° C.
