実験手順

To a solution of 1-(3-ethoxy-3-oxo-1-phenylpropyl)-1H-benzimidazole-5-carboxylic acid (50 mg, 148 μmol) in DMF (3 μL) was added N,N-diisopropylethylamine (50 μL, 287 μmol) and TBTU (57 mg, 177 μmol). The solution was stirred at room temperature for 0.5 hour, aniline (20 μL, 220 μmol) was added, and stirring continued at room temperature for 72 hours. The solution was evaporated in vacuo, and the residue was purified by flash column chromatography on silica gel, eluting with a mixture of dichloromethane and methanol (98:2) to afford the title compound, [LCMS (Method A, Mobile Phase I) RT=5.30 min, MH+ 414].
