Reaction Steps

[(1S,5S)-3-[(1R)-1-Phenylethyl]-3-azabicyclo[3.3.0]oct-7-en-1-yl]carboxylic acid tert-butyl ester (370 mg, 1.18 mmol) was dissolved in dichloroethane (3 mL). Benzyloxycarbonyl chloride (1.01 g, 5.90 mmol) was added, and the mixture was stirred at 40° C. for three 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 385 mg of the title compound as a colorless oil.
