Trifluoroacetic acid (7 ml) was added to a solution of crude N-[3-((hydroxyimino)methyl)benzyl]succinamic acid tert-butyl ester (249 mg, 0.81 mmol) in dichloromethane (7 ml). The reaction mixture was stirred for 55 min at room temperature. The solvent was removed in vacuo. The residue was redissolved in dichloromethane (50 ml). The solvent was removed in vacuo. The latter procedure was repeated twice to give 294 mg of crude N-[3-(hydroxyiminomethyl)benzyl]succinamic acid, which was used in the next step without further purification.
