Reaction Steps

Dichloro(bis{di-tert-butyl[4-(dimethylamino)phenyl]phosphoranyl})palladium (6.7 mg, 0.0095 mmol) was added to a mixture of methyl 3-(3-iodoimidazo[1,2-b]pyridazin-7-yl)benzoate (0.12 g, 0.32 mmol), N-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-N′-(2,2,2-trifluoroethyl)urea (140 mg, 0.41 mmol) and sodium carbonate (67 mg, 0.63 mmol) in 1,4-dioxane (3 mL) and water (0.3 mL) and then the reaction vessel was evacuated under reduced pressure and refilled with nitrogen 3 times. The reaction was stirred at 100° C. overnight. To this mixture was added aqueous AcCN and then filtered, washed with aqueous AcCN, dried to provide the product (0.09 g). LCMS (M+H)+: m/z=470.1
