Reaction Steps
To a solution of 3-bromo-6-chloroimidazo[1,2-b]pyridazine (2 g, 8.6 mmol) and 3-(trifluoromethyl)phenylboronic acid (1.63 g, 8.6 mmol) in dioxane/H2O (100 mL, 4:1) was added K2CO3 (2.4 g, 17.2 mmol) and Pd(PPh3) 4 (0.497 g, 0.430 mmol), the mixture was stirred at 110° C. for 3 h. The solution was concentrated, partitioned in EtOAc/H2O. The aqueous layer was washed with EtOAc (50 mL) for 3 times. The collected organic layers were dried over Na2SO4, concentrated and purified by column chromatography to give compound 6-chloro-3-(3-(trifluoromethyl)phenyl)imidazo[1,2-b]pyridazine (0.22 g, 0.739 mmol, yield 9%) as a brown solid.
