Versuchsvorschrift

To a mixture of 330 mg of the crude methyl 4-({[3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-(2-fluorophenyl)piperidin-1-yl]carbonyl}amino)-3-chlorobenzoate and 10 mL of THF-5.0 mL of methanol was added dropwise 5.0 mL of a 1 M aqueous sodium hydroxide solution at room temperature, followed by stirring overnight. It was neutralized by addition of 5.2 mL of 1 M hydrochloric acid, and then extracted with ethyl acetate, 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 (methanol-chloroform) to obtain 274 mg of 4-({[3-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-4-(2-fluorophenyl)piperidin-1-yl]carbonyl}amino)-3-chlorobenzoic acid as a pale yellow amorphous substance. ESI+: 660
