실험 절차

To a solution of allyl (5R,6S)-3-[2-{(2S)-1-allyloxycarbonyl-4-fluoropyrrolidin-2-yl}-1-methylethenyl]-6-[(1R)-1-hydroxyethyl]-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate (1.7 g), morpholine (694 μl), and triphenylphosphine (199 mg) in tetrahydrofuran (30 ml) and ethanol (10 ml) was added tetrakis(triphenylphosphine)palladium(0) (263 mg) at room temperature. After stirring for an hour, the precipitate was filtered, washed in turn with dichloromethane (3 times) and acetone (twice), and dried under reduced pressure to give (5R,6S)-3-[2-{(2S)-4-fluoropyrrolidin-2-yl}-1-methylethenyl]-6-[(1R)-1hydroxyethyl]-7-oxo-1-azabicyclo 3.2.0]hept-2-ene-2carboxylic acid (248 mg).
