実験手順

(1R,5R)-7-Fluoro-4-oxo-3-[(1R)-1-phenylethyl]-3-azabicyclo[3.3.0]octan-1-ylcarboxylic acid tert-butyl ester (705 mg, 2.03 mmol) was dissolved in methylene chloride (4 mL). Trifluoroacetic acid (4 mL) was added under ice-cooling, and then the mixture was stirred at room temperature for one hour. The reaction solution was concentrated under reduced pressure. Toluene was added to the residue, and the mixture was concentrated under reduced pressure again to give 595 mg (quantitative) of the title compound as a white solid.
