PROCEDURE

实验过程

A mixture of phenylmethyl (3S)-2-[(2R)-3-cyclopentyl-2-({formyl[(phenylmethyl)oxy]amino}methyl)propanoyl]-3-[({2-[(2S)-2,4-dimethyl-1-piperazinyl]-4-pyrimidinyl}amino) carbonyl]-1-pyrazolidinecarboxylate (236 mg, 0.325 mmol) and Pearlman's catalyst (45.6 mg, 0.065 mmol) in methanol (1.81 ml) was degassed and placed under 1 atm of H2 at ambient temperature. After 2 hrs, the reaction mixture was filtered and concentrated to give a residue which was purified by RP-HPLC to give (3S)-2-((2R)-3-cyclopentyl-2-{[formyl(hydroxy)amino]methyl}propanoyl)-N-{2-[(2S)-2,4-dimethyl-1-piperazinyl]-4-pyrimidinyl}-3-pyrazolidine carboxamide (125 mg, 0.244 mmol, 75% yield). MS (ES+) m/z 503.1 (MH+).
