Reaction Steps

Lithium hydroxide solution (1M aqueous, 358 μL, 0.358 mmol, 3 eq) was added to a solution of ethyl 2-(5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)-2-methylpropanoate (55 mg, 0.119 mmol) in THF (1 mL) and methanol (0.5 mL), and the mixture stirred for 2 hours at room temperature. The crude reaction mixture was then concentrated, acidified with HCl (1N) and sonicated to break up solids. Filtration gave 2-(5-bromo-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-ylthio)-2-methylpropanoic acid as an off-white solid (39 mg, 76%).
