Versuchsvorschrift

To a solution of methyl 6-(4-methylphenyl)-2-methylquinoline-3-carboxylate (0.99 g) in tetrahydrofuranethanol (5-5 ml) was added 2N sodium hydroxide (2 ml) at room temperature, and the mixture was stirred for 2 days. To the reaction mixture was added 1N hydrochloric acid (4 ml), and the mixture was concentrated under reduced pressure to precipitate crystals, which were collected by filtration and washed with ethanol and diethylether to give 6-(4-methylphenyl)-2-methylquinoline-3-carboxylic acid (648 mg) as colorless crystals.
