Reaction Steps

A solution of [8-chloro-2-isopropyl-4-methyl-3-(4-pyrazol-1-ylbenzyl)quinolin-5-yl]acetic acid methyl ester (0.04 g) in tetrahydrofuran (3.0 mL) was treated with 1.0 M aqueous lithium hydroxide solution (0.3 mL), and the resulting mixture was stirred at room temperature for six hours. The mixture was concentrated under reduced pressure and the pH adjusted to 4 by the addition of 0.1M aqueous hydrochloric acid (3.0 mL). The mixture was extracted with ethyl acetate and the combined extracts washed with saturated aqueous sodium chloride solution and dried over magnesium sulfate. The solvent was removed under reduced pressure and the residue purified by preparative reverse-phase HPLC, eluting with a mixture of acetonitrile and water (5:95 to 98:2 by volume) to afford title compound as white solid (0.024 g).
