To a solution of phenylmethyl (3S)-3-{[(5-fluoro-2-pyridinyl)amino]carbonyl}-2-[(2R)-2-({formyl[(phenylmethyl)oxy]amino}methyl)hexanoyl]-1-pyrazolidinecarboxylate (230 mg, 0.38 mmol) in methanol (30 mL) was added Pd(OH)2/C (230 mg). The mixture was degassed and then stirred under an H2 atmosphere for 3 h at rt. The catalyst was filtered off. The filtrate was concentrated and the residue was purified by pre-HPLC to provide the title compound (67 mg, 48%). LCMS: (M+H)+: 382.2.
