Procedure

5-Propyl-1-(2′-sulfamoylbiphenyl-4-ylmethyl)-1H-pyrazole-3-carboxylic acid ethyl ester (80 mg, 0.2 mmol) was dissolved in methylene chloride (2.0 mL, 30.6 mmol). Methyl chloroformate (17.4 μL, 224 μmol) was added, along with DIPEA (81.5 μL, 468 μmol). The mixture was stirred at room temperature for 2 hours. 1 M LiOH in water (1.5 mL, 1.50 mmol) and THF:EtOH 2:1 mL were added and the resulting mixture was stirred for 2 hours. The reaction was quenched with 1 N HCl and DCM (4 mL) was added. The organics were extracted and dried under vacuum to yield the title compound.
