Conditions

Temperature: 60 °C

Procedure

A 10 mL scintillation vial was charged with 4-(4-tert-butyl-benzenesulfonylamino)-3-(5-ethyl-4-methyl-4H-[1,2,4]triazol-3-yl)-benzoic acid methyl ester (20 mg, 0.044 mmol) and 3 M NaOH (aq)/THF (1:3) (1.5 mL). The reaction was heated to 60° C. and stirred overnight. The following day, the volatiles were removed in vacuo to about 200 μL at which point the solution was purified by preparative TLC to afford 4-(4-tert-butyl-benzenesulfonylamino)-3-(5-ethyl-4-methyl-4H-[1,2,4]triazol-3-yl)-benzoic acid as a light yellow solid: MS (ES) M+H expect 443.2, found 443.4.
