6-Chloro-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine (2 g, 8.99 mmol), methyl 4-(piperidin-4-yl)benzoate (CAS 281235-04-9, 2.168 g, 9.89 mmol) and DIPEA (3.91 mL, 22.47 mmol) were dissolved in DMA (10 mL) and sealed into a microwave tube. The mixture was heated to 110° C. for 5 minutes in the microwave reactor and cooled to room temperature. The reaction mixture was added dropwise to stirred water (30 mL), stirred for 10 minutes then the precipitate was collected by filtration, washed with ether (2×2 mL) and dried to give methyl 4-[1-[3-(trifluoromethyl)[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]benzoate (3.32 g, 91%) as a solid.
