실험 절차

Methyl 2-bromoacetate (0.418 mL, 4.42 mmol) was added to 4-[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]phenol (obtained as described in Example 513, preparation of starting materials) (1.07 g, 2.94 mmol) and potassium carbonate (0.814 g, 5.89 mmol) in DMF (20 mL). The resulting suspension was stirred at ambient temperature for 16 hours. The reaction mixture was evaporated to dryness then water (50 mL) added and stirring continued for 20 minutes. The resulting precipitate was collected by filtration, washed with water then ether and dried to afford methyl 2-[4-[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]phenoxy]acetate (1.290 g, 100%).
