実験手順

DIEA (45.5 μL, 0.26 mmol) was added to 6-chloro-2H-chromene-3-carboxylic acid (50.0 mg, 0.24 mmol) and HATU (99.3 mg, 0.26 mmol) in 2 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-Imidazo[1,2-a]pyridin-2-yl-phenylamine (49.7 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 66.6 mg of product in 69% yield: LCMS (ESI) m/z 401 (MH+).
