Versuchsvorschrift

To a stirred solution of ethyl 2-(2-(4-fluorobenzamido)phenyl)-4,4-dimethyl-1,2,3,4-tetrahydroquinoline-6-carboxylate (about 0.62 mmol) in ethanol was added a solution of lithium hydroxide monohydrate (129 mg, 3.08 mmol) and sodium hydroxide (50 mg, 1.23 mmol) in water at room temperature. The reaction mixture was concentrated in vacuo. The residue was diluted with water, adjusted pH=3˜4 by 1M aqueous hydrochloric acid, extracted with ethyl acetate. The combined organic layer was washed by brine, dried over anhydrous sodium sulfate, concentrated in vacuo. The residue was purified by HPLC to give 2-[2-(4-fluoro-benzoylamino)-phenyl]-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid LC/MS m/e obsd. (ESI+) [(M+H)+] 419.10.
