実験手順
To a solution of phenylmethyl (3S)-3-{[(5-fluoro-2-pyridinyl)amino]carbonyl}-2-[(2R)-2-({formyl[(phenylmethyl)oxy]amino}methyl)heptanoyl]-1-pyrazolidinecarboxylate (130 mg, 0.210 mmol) in dichloromethane (DCM) (4 mL) under nitrogen at 0° C. was added 3-chlorobenzenecarboperoxoic acid (141 mg, 0.629 mmol) in one portion. The reaction mixture was stirred at 0° C. for 10 min, then warmed up to room temperature and stirred overnight. The reaction was quenched by addition of sat. aq. NaHCO3 and extracted with DCM twice. The combined organic extracts were dried over Na2SO4, filtered and concentrated to afford the crude product as a white semi-solid. The crude product was purified by RP-HPLC to provide phenylmethyl (3S)-3-{[(5-fluoro-1-oxido-2-pyridinyl)amino]carbonyl}-2-[(2R)-2-({formyl[(phenylmethyl)oxy]amino}methyl)heptanoyl]-1-pyrazolidinecarboxylate (103 mg, 77%). LCMS: (M+H)+: 636.0.
