Reaktionsschritte

DIEA (0.044 mL, 0.25 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.050 g, 0.23 mmol) and HATU (0.095 g, 0.25 mmol) in 2 mL of dimethylformamide (DMF) with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-(1H-benzimidazol-2-yl)-benzenamine (0.048 g, 0.23 mmol) was added and allowed to react overnight, when a yellow solid precipitated out of solution. The precipitate was filtered and dried under suction and then in vacuo to give 1541F: LCMS (ESI) m/z 412 (MH+).
