Reaction Steps

A mixture of 3-bromothieno[2,3-d]pyridazin-4(5H)-one from Example 3.4 (231 mg, 1 mmol), 2-(7-fluoroimidazo[1,2-a]pyridin-2-yl)ethanol from Example a5 (180 mg, 1.00 mmol) and Ph3P (525 mg, 2.00 mmol) was dissolved in THF (6 mL). Then DEAD (0.317 mL, 2.00 mmol) in THF (1 mL) was added. The resulting mixture was stirred at room temperature under nitrogen overnight. The mixture was concentrated and purified on the ISCO Combiflash system using a 40 g C-18 column using the following gradient: A: Water (0.1% NH4HCO3); B: Methanol; 30% B to 80% B over 20 min (160 mg, yield: 17.7%).
