Reaction Steps
4-[3-(2,5-Dichloro-benzenesulfonylamino)-4,5-dimethoxy-benzoylamino]-benzoic acid, MS (ISP): m/e=523.1 (M−H), was prepared in analogy to example 31, steps A to D. Step C was performed using 2,5-dichloro-benzenesulfonyl chloride and yielded 4-[3-(2,5-dichloro-benzenesulfonylamino)-4,5-dimethoxy-benzoylamino]-benzoic acid ethyl ester, which was hydrolyzed in step D.
