실험 절차

To a solution of ethyl 3-{5-[(3-nitrobenzoyl)amino]-1H-benzimidazol-1-yl}-3-phenylpropanoate (190 mg, 415 μmol) in a mixture of ethanol and water (4:1, 10 mL) was added palladium on carbon (38 mg, 10% w/w Pd) and ammonium formate (130 mg, 2.06 mmol). The suspension was heated to reflux for 2 hours, cooled to room temperature and filtered through a pad of Celite®. The filtrate was then evaporated in vacuo to afford the title compound, [LCMS (Method A, Mobile Phase I) RT=3.85 min, MH+ 429].
