Procedure
3-Chloro-4-{4-[5-(1-ethyl-1H-indol-6-ylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-benzoic acid was synthesized from N-(1-ethyl-1H-indol-6-yl)-6-piperazin-1-yl-nicotinamide and 4-bromo-3-chloro-benzoic acid in a manner similar to the one described in the synthesis of 4-{4-[4-(3-tert-butyl-phenylcarbamoyl)-2-fluoro-phenyl]-piperazin-1-yl}-benzoic acid above. LCMS calcd for C27H26ClN5O3 (m/e) 503, obsd 504 (M+H).
