실험 절차
To 2.5 mmol 2-(4-methoxy-benzyloxy)-5-sulfamoyl-benzoic acid methyl ester in 6 ml THF was added 5 mmol 2 M aq NaOH, and the mixture was heated at 60° C. for 30 min. The mixture was then cooled to RT and extracted twice with ethyl acetate. The aqueous phase was acidified to pH 1 with 5 M aq HCl and extracted with ethyl acetate. The combined organic phases were washed with saturated aq NaCl and dried with Na2SO4. Evaporation in vacuo afforded the title compound. MS (m/e): 336.1 ([M−H]−, 100%)
