Procedure
4-[4-(Naphthalen-2-ylcarbamoyl)-phenyl]-piperazine-1-carboxylic acid tert-butyl ester was synthesized from 4-(4-carboxy-phenyl)-piperazine-1-carboxylic acid tert-butyl ester and naphthalen-2-ylamine in a manner similar to the one described in the synthesis of 4-[4-(3-tert-butyl-phenylcarbamoyl)-phenyl]-piperazine-1-carboxylic acid tert-butyl ester, above. LCMS calcd for C26H29N3O3 (m/e) 431, obsd 432 (M+H).
