Reaction Steps

A solution of 6-(trifluoromethyl)pyridin-2-amine (0.668 g, 4.12 mmol) in DMF (5 mL) was added NaH (0.10 g, 4.18 mmol) and stirred for 0.5 h. To the mixture was added 8-bromo-6-chloroimidazo[1,2-b]pyridazine (0.38 g, 1.65 mmol) under N2. The mixture was stirred at room temperature for 16 h then 100 mL of water was added and the precipitate collected by filtration and washed with water to give 6-chloro-N-(6-(trifluoromethyl)pyridin-2-yl)imidazo[1,2-b]pyridazin-8-amine (0.513 g, 99%) as a light brown solid. LC-MS: [M+H]+, 314.1, tR=1.738 min.
