To this mixture is added 4.46 grams (0.02 mole) of the potassium salt of 5-fluoro-2-nitrobenzoate (Formula III Compound). After stirring at about 100° C. for about 16 hours, the reaction mixture is poured into 200 milliliters of water and acidified with concentrated hydrochloric acid. Filtration and air drying affords 5-(6-chloro-2-quinolinoxy)-2-nitrobenzoic acid (Formula IV Compound).
