Participants

Reaction Steps

To a solution of ethyl 3-(5-amino-1H-benzimidazol-1-yl)-3-phenylpropanoate (250 mg, 809 μmol) in dichloromethane (15 mL) was added triethylamine (250 μL, 1.78 mmol) and 2-nitrobenzoyl chloride (240 μL, 1.78 mmol). The solution was stirred at room temperature for 110 hours, and was then evaporated in vacuo. The residue was purified by flash column chromatography on silica gel, eluting with a mixture of dichloromethane and methanol (97:3) to afford the title compound, [LCMS (Method A, Mobile Phase II) RT=5.23 min, MH+ 459].
