Reaction Steps

DIEA (0.014 mL, 0.077 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.016 g, 0.070 mmol) and HATU (0.029 g, 0.077 mmol) in 0.36 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 4′-Methoxy-3′-methyl-biphenyl-3-ylamine (0.015 g, 0.070 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 0.023 g of product in 78% yield: LCMS (ESI) m/z 416 (MH+).
