Procedure

To a solution of ethyl 2-((3-(thiophen-2-yl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)butanoate. (1 mmol) in dioxane (3 mL) was added 0.5 ml of sodium hydroxide (2N), and the reaction mixture was stirred at room temperature. After 2 hours, the mixture was evaporated to dryness, and the obtained residue dissolved in water (2 mL) and then acidified with a hydrochloric acid solution. The resulting precipitate was filtered, washed with water, and dried to give 2-((3-(thiophen-2-yl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)butanoic acid.
