실험 절차

A solution of tert-butyl 2-[4-(benzyloxy)benzoyl]hydrazinecarboxylate (975 mg, 2.85 mmol) in presence of catalytic amount of Pd—C 10% in ethanol (40 mL) is hydrogenated for 3 hours. After filtration on celite, the residue is purified on column chromatography (silica gel, 10% MeOH in CH2Cl2) and tert-butyl 2-(4-hydroxybenzoyl)hydrazine carboxylate (0.688 g, yield: 96%) was identified by NMR spectroscopy.
