Participants

Reaction Steps

A solution of [8-chloro-3-(4-chlorophenoxy)-2,4-dimethylquinolin-5-yloxy]acetic acid methyl ester (0.20 g), methanol (5.0 mL), water (1.0 mL) and 5.0 M aqueous sodium hydroxide solution (1.0 mL) was stirred at room temperature for 3 hours. The pH of the solution was adjusted to 1 by the addition of 1.0 M hydrochloric acid and the methanol removed under reduced pressure. The residue was purified by preparative reverse-phase HPLC using a gradient over 30 minutes of acetonitrile in water (40% to 98% of organic modifier) to afford title compound as a yellow-green solid, 0.025 g.
