Reaction Steps

2-Chloro-4-{[1-(3,5-dichloro-benzenesulfonyl)-4-methoxy-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid, m/z (ES+): 555.25 (M+H+.), was prepared in analogy to example 21, steps 1 to 6. Step 5 was performed using 3,5-dichloro-benzenesulfonyl chloride, yielding 2-chloro-4-{[1-(3,5-dichloro-benzenesulfonyl)-4-methoxy-2,3-dihydro-1H-indole-6-carbonyl]-amino}-benzoic acid methyl ester, which was hydrolyzed in step 6.
