実験手順

DIEA (0.013 mL, 0.077 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.015 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, 3-(2-Ethoxy-pyridin-3-yl)-phenylamine (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 0.025 g of product in 86% yield: LCMS (ESI) m/z 417 (MH+).
