반응 단계
DIEA (43.5 μL, 0.25 mmol) was added to 8-methoxy-3-carboxy-coumarin (50.0 mg, 0.23 mmol) and HATU (95.0 mg, 0.25 mmol) in 1 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 4-(1H-benzoimidazol-2-yl)-phenylamine (47.5 mg, 0.23 mmol) was added and allowed to react overnight when a solid precipitated out of solution. The resulting precipitate was filtered, dried under suction, and finally dried overnight in vacuo to give 71.0 mg of product in 75% yield: LCMS (ESI) m/z 412 (MH+).
