Reaction Steps

Potassium carbonate (0.29 g, 0.0021 mol) and 4-methylpiperidine-4-carboxylic acid ethyl ester (0.36 g, 0.0021 mol) are added to a solution of 5-(3-chloro-4-isobutylphenyl)-3-(4-chloromethylphenyl)-[1,2,4]-oxadiazole (0.5 g, 0.0014 mol) in N,N-dimethylformamide (10 mL). The reaction mixture is heated at 65-70° C. for 2 hours. Removal of solvent gives a crude residue which is purified by column chromatography (silica gel 230-400 mesh, toluene:ethyl acetate 4:1) to give 1-{4-[5-(3-chloro-4-isobutylphenyl)-[1,2,4]-oxadiazol-3-yl]-benzyl}-4-methylpiperidine-4-carboxylic acid ethyl ester.
