Procedure

DIEA (0.013 mL, 0.072 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.016 g, 0.067 mmol) and HATU (0.028 g, 0.072 mmol) in 0.36 mL of DMF with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-phenylamine (0.015 g, 0.067 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 0.022 g of product in 79% yield: LCMS (ESI) m/z 430 (MH+).
