Reaction Steps

(1S,5R)-3-Benzyloxycarbonyl-1-(tert-butoxycarbonylamino)-6-fluoromethyl-3-azabicyclo[3.2.0]heptane (derived from isomer A) (625 mg, 1.65 mmol) was dissolved in tetrahydrofuran (12 mL). 20% palladium hydroxide-carbon (50% wet) (200 mg) was added, and the mixture was stirred in a hydrogen atmosphere for one hour. The catalyst was removed by filtration, and then the filtrate was concentrated under reduced pressure. A 1 M sodium hydroxide solution was added to the residue under ice-cooling, followed by extraction with chloroform. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give 403 mg of the title compound as a colorless syrup.
