Procedure

To a solution of 1-[2,4-dichloro-3-[2-methyl-4-(pyrazol-1-yl)quinolin-8-yloxymethyl]phenyl]-2-ethoxycarbonylpyrrole (395 mg) in 1,4-dioxane (5 ml) was added 1N sodium hydroxide solution (1.8 ml), and the mixture was refluxed for 2 days. The solvent was removed in vacuo and the residue was dissolved in water. The aqueous solultion was washed with diethyl ether and adjusted to pH 5 with 1N hydrochloric acid. The mixture was extracted with chloroform, and the extract was dried over magnesium sulfate and evaporated in vacuo to give 2-carboxy-1-[2,4-dichloro-3-[2-methyl-4-(pyrazol-1-yl)quinolin-8-yloxymethyl]phenyl]pyrrole (296 mg) as amorphous powder.
