反応手順
DIEA (0.028 mL, 0.160 mmol) was added to 8-hydroxy-3-carboxy-coumarin (0.030 g, 0.146 mmol) and HATU (0.061 g, 0.160 mmol) in 0.5 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-pyridin-3-ylaniline (0.025 g, 0.146 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 0.017 g of product in 32% yield: LCMS (ESI) m/z 359 (MH+).
