反応手順
DIEA (0.044 mL, 0.25 mmol) was added to 8-methoxy-3-carboxy-coumarin (0.030 g, 0.14 mmol) and HATU (0.095 g, 0.25 mmol) in 1 mL of dimethylformamide (DMF) with constant stirring at room temperature until a clear solution resulted. Subsequently, pyrimidin-4-ylamine (0.009 g, 0.09 mmol) was added and allowed to react overnight, when a solid precipitated out of solution. The precipitate was filtered and dried under suction and then in vacuo to give 0.003 g of 1541E in an 11% yield: LCMS (ESI) m/z 298 (MH+).
