실험 절차

To a solution of methyl 3-{4-[[(2′,6′-dimethylbiphenyl-3-yl)methyl](propyl)amino]phenyl}propanoate (0.735 g, 1.77 mmol) in a mixture of methanol (8 mL) and tetrahydrofuran (8 mL) was added 2 M aqueous sodium hydroxide solution (2.5 mL), and the mixture was stirred at room temperature for 19 hr. Water was added to the reaction mixture, and the mixture was weakly acidified with 10% aqueous citric acid solution and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20%-70% ethyl acetate/hexane) to give the title compound (0.710 g, yield 99%) as a yellow oil.
