Versuchsvorschrift

To 232 mg of 4-(methoxycarbonyl)phenyl 3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpiperidine-1-carboxylate were added 6.0 mL of THF, 3.0 mL of methanol, and 3.0 mL of a 1 M aqueous sodium hydroxide solution, followed by stirring at room temperature overnight. After neutralizing by addition of 3.0 mL of 1 M hydrochloric acid, the reaction mixture was concentrated under reduced pressure. To the residue was added water, followed by extraction with chloroform, and the organic layer was dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform-methanol). This was dissolved in a small amount of chloroform, and hexane was added thereto. Then, the precipitate was isolated by filtration, and dried under reduced pressure at 50° C. to obtain 66 mg of 4-({[3-({[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-phenylpiperidin-1-yl]carbonyl}oxy)benzoic acid as a white solid.
