Reaction Steps

500 mg (0.95 mmol) of 4-((2-(4-chloro-phenylsulfonylamino)-4,5-dimethoxy-benzoyl)-amino)-benzenesulfonyl fluoride were dissolved in 1 ml of thiomorpholine and heated to 90° C. for 30 min. For working up the mixture was poured onto 50 ml of ice/1 N hydrochloric acid, the precipitate was filtered off with suction, dried in a vacuum-drying chamber over phosphorus pentoxide and recrystallized from hexane/ethyl acetate. 378 mg (65%) of the title compound having a melting point of 241° C. were obtained.
