Participants

Reaction Steps

To ethyl 2-((3-(thiophen-2-yl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)acetate (50 mg, 0.156 mmol) dissolved in a 2/1 mixture of THF and MeOH was added 100 uL of 2N NaOH, and the whole was stirred at room temperature for 3 h. The reaction mixture was then evaporated to dryness, the residue dissolved in water (5 mL), and the solution acidified with 6M HCl. The resulting precipitate was filtered, washed twice with cold water, and dried to give acid 2-((3-(thiophen-2-yl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)acetic acid.
