Reaction Steps

Lithium hydroxide monohydrate (0.622 g, 14.81 mmol) was added to 2-[4-[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]phenoxy]acetate (1.29 g, 2.96 mmol) in a mixture of THF (20 mL), water (10 mL) and MeOH (5 mL). The resulting mixture was stirred at ambient temperature for 16 hours. The solvents were evaporated then the residues were suspended in water and acidified to pH 4 with 1M citric acid. The resulting precipitate was collected by filtration, washed with water and dried to afford 2-[4-[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]phenoxy]acetic acid (1.020 g, 82%).
