実験手順

DIEA (38.3 μL, 0.22 mmol) was added to 7,8-dimethoxy-3-carboxy-coumarin (500 mg, 0.20 mmol) and HATU (83.6 mg, 0.22 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 (41.8 mg, 0.20 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 68.7 mg of product in 78% yield: LCMS (ESI) m/z 442 (MH+).
