実験手順

Ethyl 5-(4-chlorophenyl)-4-((dimethylamino)methyl)-3-(4-(N-((dimethylamino)methylene)sulfamoyl)phenyl)thiophene-2-carboxylate (compound 35c, 1.0 g, 1.87 mmol) was suspended in ethanol (20 ml) and a solution of NaOH (0.37 g, 9.36 mmol) in water (2 ml) was added to it at 25° C. The reaction mixture was heated at 75° C. under stirring for 2 hr. The progress of the reaction was monitored by TLC. The reaction mixture was concentrated under reduced pressure. The residue so obtained was then diluted with water (5 ml) and cooled using ice bath. To the cooled mixture was then added aqueous 10% HCl to bring pH of the mixture to between 5 and 6. The resulting solid was filtered and dried under reduced pressure to obtain the title compound (0.8 g, 94.78%).
