실험 절차

3-(3-Phenylsulfamoylphenyl)acrylic acid methyl ester (4a) (0.220 g, 0.69 mmol) was dissolved in methanol (3 ml), 1N NaOH (2.08 ml, 2.08 mmol) was added and the resultant solution was stirred at ambient temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The aqueous layer was acidified with 10% HCl and stirred for 30 min. The precipitated solid was filtered, washed with water and dried in desiccator over P2O5 to give the title compound as a white solid (0.173 g, 82%).
