Reaction Steps

DIEA (0.030 mL, 0.17 mmol) was added to 8-(4-morpholinylmethyl)-3-carboxy-6-methoxy-coumarin (0.050 g, 0.16 mmol) and HATU (0.065 g, 0.17 mmol) in 1 mL of dimethylformamide (DMF) with constant stirring at room temperature until a clear solution resulted. Subsequently, 3-imidazo[1,2-a]pyridin-2-yl-phenylamine (0.033 g, 0.16 mmol) was added and allowed to react overnight, when a yellow solid precipitated out of solution. The precipitate was filtered and dried under suction and then in vacuo to give 0.047 g of 1541D in a 59% yield: LCMS (ESI) m/z 511 (MH+).
