実験手順

(2S,4S)-1-[[N-Benzyloxycarbonyl-N-[4-(piperidin-1-yl)carbonylbicyclo[2.2.2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (20.0 mg) and 10% palladium carbon (12.0 mg) were dissolved in dimethylformamide (0.5 mL). While the solution was chilled in an ice bath, ammonium formate (43.1 mg) was added and the mixture was stirred for 40 minutes at the same temperature. Subsequently, the reaction mixture was filtered through a Celite pad and diluted with ethyl acetate. The organic layer washed sequentially with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by column chromatography (eluant:dichloromethane:methanol=10:1) to give (2S,4S)-1-[[N-[4-(piperidin-1-yl)carbonylbicyclo[2.2.2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (13.2 mg).
