Reaktionsschritte

DIEA (0.012 mL, 0.071 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.014 g, 0.065 mmol) and HATU (0.027 g, 0.071 mmol) in 0.5 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-(5-methoxy-pyridin-3-yl)-phenylamine (0.013 g, 0.065 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 0.020 g of product in 79% yield: LCMS (ESI) m/z 403 (MH+).
