Reaction Steps

A solution of [3-(4-chlorobenzyl)-4-difluoromethoxy-2-ethyl-8-fluoroquinolin-5-yloxy]acetic acid methyl ester (0.11 g), methanol (10 mL), and 5.0 M aqueous sodium hydroxide solution (1.0 mL) was stirred at room temperature for 30 minutes. The pH of the solution was adjusted to 5 by the addition of glacial acetic acid. The solvent was removed under reduced pressured and the residue purified by preparative reverse-phase HPLC using a gradient over 30 minutes of acetonitrile in water (40% to 95% of organic modifier) to afford title compound as a white solid, 0.040 g.
