Procedure

DIEA (46.5 μL, 0.27 mmol) was added to 6-hydroxy-3-carboxy-coumarin (50.0 mg, 0.24 mmol) and HATU (101.4 mg, 0.27 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 (50.8 mg, 0.24 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 81.1 mg of product in 85% yield: LCMS (ESI) m/z 398 (MH+).
