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, 3-Imidazo[1,2-a]pyridin-2-yl-phenylamine (38.7 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 65.0 mg of product in 76% yield: LCMS (ESI) m/z 373 (MH+).
