実験手順

DIEA (0.014 mL, 0.078 mmol) was added to 8-trifluoromethoxy-3-carboxy-coumarin (0.020 g, 0.071 mmol) and HATU (0.030 g, 0.078 mmol) in 0.36 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-(2,3-dihydro-benzofuran-5-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 0.026 g of product in 76% yield: LCMS (ESI) m/z 484 (MH+).
