実験手順

To a solution of 180 mg of methyl 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]hexanoate in 2.0 mL of methanol was added 1.00 mL of a 1 M aqueous sodium hydroxide solution at room temperature, followed by stirring for 1 hour. It was neutralized by addition of 1.00 mL of 1 M hydrochloric acid, and then extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 168 mg of 6-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]hexanoic acid. ESI+: 577
