Reaction Steps

To a solution of 3-bromo-6-chloroimidazo[1,2-b]pyridazine (2 g, 8.6 mmol) and 3-(cyano)phenylboronic acid (1.26 g, 8.6 mmol) in dioxane/H2O (100 mL, 4:1) was added K2CO3 (2.38 g, 17.2 mmol) and Pd(PPh3)4 (0.19 g, 0.172 mmol), the mixture was stirred at 110° C. for 3 h. The solution was concentrated and partitioned in EtOAc/H2O. The aqueous layer was washed with EtOAc (50 mL) 3 times. The collected organic layers were dried over Na2SO4, concentrated and purified by column chromatography to give compound 3-(6-chloroimidazo[1,2-b]pyridazin-3-yl)benzonitrile (1.2 g, 4.71 mmol, yield 55%) as a brown solid.
