実験手順

4-Benzyloxycarbonylamino-N-(4,4-difluorocyclohexyl)bicyclo[2.2.2]octane-1-carboxamide (55.4 mg) was dissolved in tetrahydrofuran (6 mL). To this solution, 10% palladium carbon (20.0 mg) was added and the mixture was stirred at room temperature for 6 hours in a hydrogen atmosphere. The reaction mixture was filtered to remove the catalyst and the filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column (eluant:ethyl acetate:methanol=10:1) to give 4-amino-N-(4,4-difluorocyclohexyl)bicyclo[2.2.2]octane-1-carboxamide (38.1 mg) as a white solid.
