Reaction Steps

To a solution of 6-chloroimidazo[1,2-b]pyridazine (606 mg, 3.95 mmol, 1.0 equiv) in toluene (10.00 mL) was added 2-bromo-5-chloro-3-methylbenzo[b]thiophene (1.03 g, 3.95 mmol, 1.0 equiv), potassium carbonate (1.09 g, 7.90 mmol, 2.0 equiv), triphenyl phosphine (207 mg, 0.790 mmol, 0.20 equiv) and potassium acetate (89 mg, 0.395 mmol, 0.1 equiv). The reaction mixture was heated to reflux for 24 h. Purification by column chromatography using 50% ethyl acetate in hexanes elution gave 500 mg of the white solid, 38%.
