Versuchsvorschrift

Isobutyl chloroformate (0.158 mL, 0.0012 mol) is added to a solution of 1-{4-[5-(2-fluoro-biphenyl-4-yl)-[1,2,4]oxadiazol-3-yl]-benzyl}-piperidine-4,4-dicarboxylic acid benzyl ester (0.6 g, 0.0010 mol) and N-methyl morpholine (0.156 mL, 0.0015 mol) in tetrahydrofuran (20 mL) at 5° C. The reaction mixture is stirred at 5° C. for 45 minutes. 1-Amino piperidine (0.162 mL, 0.0015 mol) is added to the reaction mixture and is stirred for 30 minutes at 5° C. and then at room temperature for 45 minutes. Demineralized water (10 mL) is added to the reaction mixture, Organic layer is separated and dried over sodium sulphate. Removal of solvent under reduced pressure gives a viscous liquid, which is purified by column chromatography (silica gel 230-400 mesh, hexane:ethyl acetate 70:30) to get 1-{4-[5-(2-fluoro-biphenyl-4-yl)-[1,2,4]oxadiazol-3-yl]-benzyl}-4-(piperidine-1-ylcarbamoyl)-piperidine-4-carboxylic acid benzyl ester.
