Reaction Conditions

Reaction Steps

Potassium carbonate (0.28 g, 0.002 mol) and 4-methoxymethylpiperidine-4-carboxylic acid ethyl ester (0.4 g, 0.002 mol) are added to a solution of 5-(3-Chloro-4-cyclopentylphenyl)-3-(4-chloromethyl-phenyl)-[1,2,4]oxadiazole (0.5 g, 0.0013 mol) in N,N-dimethylformamide (15 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-cyclopentylphenyl)-[1,2,4]-oxadiazol-3-yl]benzyl}-4-methoxy methyl piperidine-4-carboxylic acid ethyl ester.
