Reaction Steps

Aqueous lithium hydroxide solution (1M, 437 μL, 0.437 mmol, 3 eq.) was added to a solution of ethyl 3-(5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)propanoate (65 mg, 0.146 mmol) in THF (1.5 mL) and methanol (1 mL). The mixture was stirred at room temperature for ˜2 hours, and HCl (1N, 584 μL, 0.584 mmol, 4 eq.) added. The mixture was concentrated, a little water added, sonicated and the off-white solids isolated by filtration. The isolated material was placed into small amount of methanol, sonicated again, and then filtered to give 5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazole-3-thiol as an off-white solid (39 mg, 78%).
