Versuchsvorschrift

To a stirred solution of 3-[4-(2-chloro-phenoxy)-piperidin-1-yl]-3-oxo-propionic acid (0.08 g, 0.00027 mole) in DMF (3 mL) was added DMAP (0.049 g, 0.00040 mole), HOBt (0.043 g, 0.00032 mole) and EDCI.HCl (0.06 g, 0.00032 mole). After 2 minutes 6-phenyl-pyridin-3-ylamine (0.055 g, 0.00032 mole) was added and the resulting mixture was stirred overnight. The reaction mixture was then diluted with cold water and the product was extracted with ethyl acetate ethyl acetate. The organic layer was washed with brine solution, dried over sodium sulfate and concentrated under reduced pressure to afford 0.0642 g (53%) of 3-[4-(2-chloro-phenoxy)-piperidin-1-yl]-3-oxo-N-(6-phenyl-pyridin-3-yl)-propionamide. LC-MS purity: 450.15 (M+1)+, 99.25%, 1H NMR (DMSO-d6): δ 10.4 (s, 1H), 8.8 (s, 1H), 8.2 (dd, 1H), 8.1-8.0 (m, 2H), 8.0-7.9 (m, 1H), 7.5-7.2 (m, 6H), 7.0-6.9 (m, 1H), 4.8-4.7 (m, 1H), 3.8-3.7 (m, 2H), 3.7-3.6 (s, 2H), 3.6-3.5 (m, 2H), 2.1-1.5 (m, 4H).
