To a solution of 6-chloro-3-(1-(6-fluoro-1-methyl-1H-indazol-5-yl)ethyl)imidazo[1,2-b]pyridazine (900 mg, 1.910 mmol) in DMF (8 mL) was added Pd(Ph3P)4 (221 mg, 0.191 mmol). The mixture was stirred for 20 min, and tributyl(1-ethoxyvinyl)stannane (784 mg, 2.102 mmol) was added. The resulting mixture was heated at 100° C. until LC-MS showed the reaction was complete. The reaction mixture was filtered through celite and the solid was washed with ether. The combined filtrate was washed with water, dried over Na2SO4, and concentrated. The residue was purified by column chromatography with gradient hexane:EtOAc to give 450 mg (52%) of the title compound.
