실험 절차

To a solution of 177 mg of ethyl 4-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]-4-oxobutanoate in 2.0 mL of ethanol was added 1.00 mL of a 1 M aqueous sodium hydroxide solution at room temperature, followed by stirring for 2 hours. It was neutralized by addition of 1.00 mL of 1 M hydrochloric acid. It was extracted with ethyl acetate, and the organic layer was washed with saturated brine, and then dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 174 mg of 4-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]-4-oxobutanoic acid as a colorless oily compound. ESI+: 563
