Reaction Conditions

Reaction Steps

Aqueous sodium hydroxide solution (1M, 2.0 mL, 2.0 mmol) was added dropwise over 5 min to a solution of 2-(5-bromo-4-(1-cyclopropylnaphthalen-4-yl)-4H-1,2,4-triazol-3-ylthio)acetic acid (810 mg, 2.0 mmol) in ethanol (10 mL) at 10° C. The mixture was stirred at 10° C. for a further 10 min. Volatile solvents were removed in vacuo to dryness to provide sodium 2-(5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)acetate as a solid (850 mg, 100%).
