Procedure
A solution of [8-chloro-3-(4-chlorobenzyl)-2-methylquinolin-5-yloxy]acetic acid methyl ester (0.10 g), ethanol (6.0 mL), water (2.0 mL) and saturated aqueous lithium hydroxide solution (2.0 mL) was stirred at room temperature for 5 hours. The ethanol was removed under reduced pressure and the pH of the residue adjusted to 4 by the addition of glacial acetic acid. The resulting precipitate was collected by filtration, washed with water and purification by preparative reverse-phase HPLC using a gradient over 37 minutes of acetonitrile in water (20% to 95% of organic modifier) gave title compound as an off-white solid, 0.039 mg.
