Participants

Reaction Steps

4-{[1-(3,5-Dichloro-benzenesulfonyl)-1,2,3,4-tetrahydro-quinoline-7-carbonyl]-amino}-2-fluoro-benzoic acid, m/z (ES+): 523.18 (M+H+.), was prepared in analogy to example 48, steps 1 to 5. Step 4 was performed using 3,5-dichloro-benzenesulfonyl chloride, yielding 4-{[1-(3,5-dichloro-benzenesulfonyl)-1,2,3,4-tetrahydro-quinoline-7-carbonyl]-amino}-2-fluoro-benzoic acid ethyl ester, which was hydrolyzed in step 5.
