Reaction Steps

A mixture of [8-chloro-2-ethyl-3-(4-fluorobenzyl)-4-hydroxy-1,4-dihydroquinolin-5-yloxy]acetic acid methyl ester (0.25 g), N,N-dimethylformamide (1.1 mL), potassium carbonate (0.51 g) and acetic acid chlorodifluoromethyl ester (0.33 mL) was stirred at 70° C. for 16 hours. The mixture was diluted with water, extracted with ethyl acetate and the combined extracts dried over sodium sulfate and then the solvent removed under reduced pressure. Purification of the residue by column chromatography on silica gel, eluting with dichloromethane gave title compound, 0.06 g.
