실험 절차

[(1S,5S)-4-Oxo-3-[(1R)-1-phenylethyl]-3-azabicyclo[3.3.0]oct-7-en-1-yl]carboxylic acid tert-butyl ester (88.0 mg, 0.27 mmol) was dissolved in toluene (8 mL). Lawesson's reagent (81.5 mg, 0.20 mmol) was added, and the mixture was stirred at 80° C. for four hours. The reaction solution was concentrated under reduced pressure, and the resulting residue was subjected to silica gel column chromatography (10% ethyl acetate/hexane) to give 91.6 mg of the title compound as a yellow oil.
