実験手順

A solution of [8-chloro-2-difluoromethoxy-3-(4-methanesulfonylbenzyl)-4-methylquinolin-5-yl]acetic acid methyl ester (0.030 g), methanol (2.0 mL), saturated aqueous lithium hydroxide solution (0.20 mL) and water (0.40 mL) was stirred at room temperature for 2.5 hours and then at 40° C. for 2 hours. The pH of the solution was adjusted to 5 by the addition of glacial acetic acid and the solvent removed under reduced pressure. The residue was diluted with water and the solid collected by filtration, washed with water and methanol and then dried to afford title compound as a white solid, 0.016 g.
