Participants

Reaction Steps

The above ester (230 mg, 0.434 mmol) was dissolved in 7 mL of MeOH. A solution of 250 mg (5.99 mmol) of LiOH in 2 mL of water was added at RT. The resulting mixture was stirred overnight, then acidified with 4N HCl and extracted with EtOAc (4×30 mL). The extracts were combined, dried over MgSO4, filtered and concentrated to provide 223 mg of 1-[5-(5-tert-Butyl-2-methoxy-3-methylsulfamoyl-phenylcarbamoyl)-2-methyl-phenyl]-1H-[1,2,3]triazole-4-carboxylic acid as a brown foam (>90% by LCMS).
