Reaction Steps

200 mg (0.375 mmol) {1-[4-(3-Bromo-2-methyl-7-phenyl-imidazo[1,2-b]pyridazin-6-yl)-phenyl]-cyclobutyl}-carbamic acid tert.-butyl ester, (intermediate example Int-2-3), 53.3 mg (0.75 mmol) acrylamide, 19.4 mg (0.064 mmol) tri-2-tolylphosphane, 16.8 mg (0.075 mmol) palladium(II) acetate and 0.06 mL (0.427 mmol) triethylamine in 2.6 mL degassed acetonitrile were heated in the microwave at 110° C. for three hours. The reaction mixture was poured on water/saturated ammonium chloride/dichloromethane and vigorously stirred for 30 minutes. The organic phase was separated, washed with brine, dried, and the solvent was removed. The crude product (247 mg) was used in the next step without further purification.
