실험 절차
To a stirred mixture solution of 2-(4′-tert-butyl-biphenyl-3-yl)-6-chloro-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid methyl ester (600 mg, 1.3 mmol) in methanol (5.0 mL) and tetrahydrofuran (6.0 mL) was added 50% sodium hydroxide in water (2.0 mL). The reaction mixture was stirred at 70° C. for 6 hours. 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% ammonium hydroxide in water) afforded 2-(4′-tert-butyl-biphenyl-3-yl)-6-chloro-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid (524 mg, 90%) as a white solid: LC/MS m/e calcd for C28H30ClNO2 (M+H)+: 449.01, observed: 448.1.
