Reaction Steps

DIEA (0.008 mL, 0.048 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.009 g, 0.043 mmol) and HATU (0.018 g, 0.048 mmol) in 0.5 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-(6-hydroxy-pyridin-3-yl)-phenylamine (0.008 g, 0.043 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 0.003 g of product in 21% yield: LCMS (ESI) m/z 389 (MH+).
