Reaction Steps

2-Chloro-4-{[1-(3,4-dichloro-benzenesulfonyl)-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid, m/z (ES+): 525.18 (M+H+.), was prepared in analogy to example 1, steps 1 to 5. Step 4 was performed using 3,4-dichloro-benzenesulfonyl chloride and yielded 2-chloro-4-{[1-(3,4-dichloro-benzenesulfonyl)-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid methyl ester, which was hydrolyzed in step 5.
