실험 절차

To a solution of 48 mg of methyl 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]-1H-benzimidazole-6-carboxylate 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, and then stirring at 80° C. for 6 hours. The reaction mixture was cooled to room temperature, 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 19 mg of 2-[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]-1H-benzimidazole-6-carboxylic acid as a pale yellow amorphous compound. ESI+: 623
