A mixture of 4-[1-[3-(trifluoromethyl)[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]benzoic acid (79 mg, 0.20 mmol), N-(2-methoxyethyl)methylamine (21 mg, 0.24 mmol), DIPEA (0.105 mL, 0.61 mmol) and HATU (92 mg, 0.24 mmol) in DMA (3 mL) was stirred at ambient temperature for 16 hours. The reaction mixture was purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5μ silica, 19 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% ammonia) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to give N-(2-methoxyethyl)-N-methyl-4-[1-[3-(trifluoromethyl)[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]benzamide (77 mg, 82%) as a solid.
