Reaction Steps

6-Chloro-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine (160 mg, 0.72 mmol), 3-(piperidin-4-yl)-1H-pyrrolo[2,3-b]pyridine (145 mg, 0.72 mmol) and DIPEA (0.14 mL, 0.79 mmol) in DMF (2.0 mL) were stirred and heated at 80° C. for 1 hour. The resulting mixture was then cooled to ambient temperature and quenched in water (10 mL) to give a beige solid. The solid was collected by filtration, washed sequentially with water, acetonitrile and ether, and air dried to give 6-[4-(1H-pyrrolo[2,3-b]pyridin-3-yl)piperidin-1-yl]-3-(trifluoromethyl)[1,2,4]triazolo[4,3-b]pyridazine (217 mg, 78%) as a colourless solid.
