Versuchsvorschrift

Benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (0.266 g, 0.602 mmol) was added to a solution of 4-(2-fluoro-benzyl)-piperidine-4-carboxylic acid [2-(4-ethyl-phenyl)-ethyl]-amide (0.185 g, 0.502 mmol), 3-(4-fluoro-phenyl)-propionic acid (0.101 g, 0.602 mmol) and triethylamine (0.210 mL, 1.51 mmol) in tetrahydrofuran (5 mL). After 1 h the mixture was diluted with ethyl ether (20 mL), washed with saturated aqueous sodium bicarbonate (20 mL) followed by water (2×10 mL). The organic layer was collected, concentrated under reduced pressure and the crude product purified by column chromatography to give 0.105 g (40%) of 4-(2-fluoro-benzyl)-1-[3-(4-fluoro-phenyl)-propionyl]-piperidine-4-carboxylic acid [2-(4-ethyl-phenyl)-ethyl]-amide LRMS m/z 519.2 (M+H)+.
