Reaction Steps
DIEA (0.015 mL, 0.085 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.017 g, 0.077 mmol) and HATU (0.032 g, 0.085 mmol) in 0.45 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 2′-cyano-biphenyl-3-ylamine (0.015 g, 0.077 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 0.026 g of product in 85% yield: LCMS (ESI) m/z 397 (MH+).
