Procedure

To a suspension of 3-(3-p-tolylsulfamoyl-phenyl)-acrylic acid methyl ester (4d) (0.89 g, 2.70 mmol) in methanol (12 ml) 1N NaOH solution (8.10 ml, 8.10 mmol) was added and the resultant mixture was stirred at ambient temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The aqueous layer was acidified with 2N HCl solution 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 (0.75 g, 87%).
