Reaction Steps

4-{[1-(3,4-Dichloro-benzenesulfonyl)-4-methoxy-2,3-dihydro-1H-indole-6-carbonyl]-amino}-2-fluoro-benzoic acid, m/z (ES+): 539.27 (M+H+.), was prepared in analogy to example 14, steps 1 to 6. Step 5 was performed using 3,4-dichloro-benzenesulfonyl chloride and yielded 4-{[1-(3,4-dichloro-benzenesulfonyl)-4-methoxy-2,3-dihydro-1H-indole-6-carbonyl]-amino}-2-fluoro-benzoic acid ethyl ester, which was hydrolyzed in step 6.
