(2S,4S)-1-[[N-Benzyloxycarbonyl-N-[4-(piperidin-1-yl)carbonylbicyclo[2.2.2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (30.0 mg) and 10% palladium carbon (3.0 mg) were dissolved in ethanol (1.0 mL) and dichloromethane (0.5 mL). The mixture was stirred at room temperature for 8 hours in a hydrogen atmosphere. The mixture was then filtered through a Celite pad and the solvent was concentrated under reduced pressure. The resulting residue was purified by column chromatography (eluant:dichloromethane:methanol=10:1) to give (2S,4S)-1-[[N-[4-(pyrrolidin-1-yl)carbonylbicyclo[2.2.2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (15.2 mg).
