Procedure

DIEA (0.011 mL, 0.065 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.013 g, 0.059 mmol) and HATU (0.025 g, 0.065 mmol) in 0.36 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 2′-trifluoromethoxy-biphenyl-3-ylamine (0.015 g, 0.059 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 0.021 g of product in 76% yield: LCMS (ESI) m/z 456 (MH+).
