Procedure

A mixture of [3-(4-chlorobenzyl)-8-fluoro-4-methyl-2-oxo-1,2-dihydroquinolin-5-yloxy]acetic acid methyl ester (1.0 g), N7N-dimethylformamide (15 mL), potassium carbonate (0.89 g) and acetic acid chlorodifluoromethyl ester (1.1 mL) was stirred at 70° C. for 18 hours. The mixture was diluted with water, extracted with ethyl acetate and the combined extracts dried over magnesium sulfate. The solvent was removed under reduced pressure and purification of the residue by column chromatography on silica gel, eluting with a mixture of pentane and dichloromethane (4:1 by volume) gave title compound as a white solid, 0.49 g.
