695 mg of tert-butyl {[4-(2-fluorophenyl)-1-(trifluoroacetyl)piperidin-3-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate was dissolved in 5 mL of THF-2 mL of methanol, and 1 mL of a 1 M aqueous sodium hydroxide solution was added thereto, followed by stirring at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, and chloroform was added to the obtained residue, followed by drying over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 636 mg of a colorless foamy substance of tert-butyl {[4-(2-fluorophenyl)piperidin-3-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate as a crude product.
