실험 절차

Ethyl 5-(4-chlorophenyl)-3-(4-sulfamoylphenyl)thiophene-2-carboxylate (compound 33b, 1.3 g, 3.08 mmol) was suspended in ethanol (30 ml) and solution of NaOH (0.61 g, 15.4 mmol) in water (3 ml) was added to it at 25° C. The reaction mixture was then heated at about 75° C. under stirring for 3 hr. The progress of the reaction was monitored by TLC. The reaction mixture was then concentrated under reduced pressure. The residue so obtained was diluted with water (5 ml) and cooled using ice bath. To the cooled mixture was then added aqueous 10% HCl to bring pH to between 5 and 6. The mixture so obtained was extracted with ethyl acetate (3×25 ml). The combined organic layer was dried over anhydrous Na2SO4. The solvent was evaporated from the dried organic layer under reduced pressure to obtain the title compound (1.10 g, 90.9%).
