Procedure

Lithium hydroxide solution (1M aqueous, 0.59 mL, 0.59 mmol) is added to a solution of ethyl 2-(5-(fluoromethyl)-4-(4-methyl-5,6,7,8-tetrahydronaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)acetate (107 mg, 0.294 mmol) in THF/water (3/1, 1.2 mL) and the mixture stirred at room temperature for 18 h. The crude reaction mixture is concentrated, acidified with HCl (1N, 3 mL) and extracted with ethyl acetate (3×3 mL). The combined organic extracts are dried over sodium sulfate, filtered and concentrated to afford 2-(5-(fluoromethyl)-4-(4-methyl-5,6,7,8-tetrahydronaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)acetic acid.
