A solution of 6-chloro-3-[1-(4,6-difluoro-1-methyl-1H-indazol-5-yl)-ethyl]-imidazo[1,2-b]pyridazine (80 mg, 0.23 mmol) and tributyl(1-ethoxyvinyl)stannane (0.234 mL, 0.69 mmol) in 15 mL DMF was purged with N2 for 30 min and then tetrakis-(triphenylphosphine)-palladium (80 mg, 0.069 mmol) was added, and the solution was heated at 95° C. for overnight. Then the reaction was quenched with water, extracted with EtOAc for three times. The organic layers were combined, washed with KF solution and brine, dried over Na2SO4. Solvent was evaporated and the crude product (80 mg, 90%) was used in the next step without further purification. LCMS (method C): [MH]+=384.0, tR=4.67 min
