Procedure

To a solution of 5,6-dimethoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-indole (120 mg, 0.262 mmol, 1.0 equiv) in acetonitrile (3.41 mL) was added 6-chloro-3-iodoimidazo[1,2-b]pyridazine (95 mg, 0.341 mmol, 1.3 equiv), palladium catalyst (25 mg, 0.0341 mmol, 0.1 equiv) and sodium carbonate (3.41 mL, 1.0 M, 10.0 equiv). The solution was stirred at 150° C. in the microwave for 10 minutes. Purification using column chromatography gave 80 mg of the yellow solid, 63%.
