실험 절차

To a solution of 66 mg of methyl 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-6-chloroisonicotinate in 2.0 ml of THF and 1.0 mL of methanol was added 1.00 mL of a 1 M aqueous sodium hydroxide solution at room temperature, followed by stirring overnight. 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 68 mg of 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-phenylpiperidin-1-yl]-6-chloroisonicotinic acid as a pale yellow resinous compound. ESI+: 600
