Versuchsvorschrift

DIEA (35.6 μL, 0.2 mmol) was added to 8-bromo-3-carboxy-coumarin (50 mg, 0.19 mmol) and HATU (77.73 mg, 0.2 mmol) in 1 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-Imidazo[1,2-a]pyridin-2-yl-phenylamine (38.89 mg, 0.19 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 the final product: LCMS (ESI) m/z 461 (MH+).
