실험 절차

To a solution of ethyl 3-{6-[(4-nitrobenzoyl)amino]-1H-benzimidazol-1-yl}-3-phenylpropanoate (241 mg, 526 μmol) in a mixture of ethanol and water (6:1, 14 mL) was added palladium on carbon (48 mg, 10% w/w Pd) and ammonium formate (200 mg, 3.18 mmol). The suspension was heated to reflux for 2 hours, and was then cooled to room temperature, and filtered through a pad of Celite®. The filtrate was evaporated in vacuo to afford the title compound, [LCMS (Method A, Mobile Phase II) RT=4.61 min, MH+ 429].
