Procedure
1-[4-(1-Ethyl-1H-indol-6-ylcarbamoyl)-phenyl]-piperidine-4-carboxylic acid was prepared by the hydrolysis of 1-[4-(1-ethyl-1H-indol-6-ylcarbamoyl)-phenyl]-piperidine-4-carboxylic acid ethyl ester with LiOH monohydrate in a manner similar to the one described in the synthesis of 5′-(4-iodo-3-methyl-phenylcarbamoyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid above.
