실험 절차

A solution of 1.0 g (5.8 mmol) of p-aminophenylsulfonamide in 3.6 mL of pyridine was added 878 μL (6.1 mmol) of phthalic dichloride. After heating to 60° C. for 18 h, the solution was poured into 1N HCl, cooled to 0° C., the precipitate was collected by filtration, and dried under vacuum to give 1.58 g (90%) of the titled compound.
