Procedure
4-{4-[4-(3-tert-Butyl-phenylcarbamoyl)-3-fluoro-phenyl]-piperazin-1-yl}-benzoic acid was synthesized by the coupling of N-(3-tert-butyl-phenyl)-2-fluoro-4-piperazin-1-yl-benzamide and 4-bromo 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 C28H30FN3O3 (m/e) 475, obsd 476 (M+H).
