실험 절차

A mixture of 2-[3-(1-methoxycarbonyl-1-methyl-ethylamino)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (678 mg, 1.6 mmol) in methanol (10 mL) and tetrahydrofuran (30 mL), 30% sodium hydroxide in water (10 mL) was stirred at 60° C. for 12 h. The mixture was neutralized with a 3 N aqueous hydrochloric acid solution and extracted with ethyl acetate (2×100 mL), washed with water, dried over anhydrous sodium sulfate and then concentrated in vacuo. Purification by Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% formic acid in water) afforded 2-[3-(1-carboxy-1-methyl-ethylamino)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (30 mg, 4%) as a white solid: LC/MS m/e calcd for C22H26N2O4 (M+H)+: 383.46, observed: 383.1.
