Versuchsvorschrift

To a stirred solution of [(5-phenyl-pyridine-2-carbonyl)-amino]-acetic acid (0.07 g, 0.00027 mol) in DMF (1.5 mL) was added DIPEA (0.105 g, 0.000819 mol), HOBt (0.044 g, 0.00033 mol) and EDCI.HCl (0.062 g, 0.00033 mol) at ambient temperature. After 2 minutes 4-(2-chloro-5-fluoro-phenoxy)-piperidine hydrochloride (0.087 g, 0.00033 mol) was and the resulting mixture was stirred overnight. The reaction mixture was then diluted with cold water and the product was extracted with ethyl acetate. The ethyl acetate layer was washed with brine solution, dried over sodium sulfate and concentrated under reduced pressure afford 0.069 g (54%) of 5-phenyl-pyridine-2-carboxylic acid {2-[4-(2-chloro-5-fluoro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 468.14 (M+1)+, 82.99%, 1H NMR (DMSO-d6): δ 9.0 (d, 1H), 8.8 (t, 1H), 8.3 (dd, 1H), 8.1 (d, 1H), 7.8 (d, 2H), 7.6-7.4 (m, 4H), 7.2 (dd, 1H), 6.9-6.8 (m, 1H), 4.9-4.8 (m, 1H), 4.3 (d, 2H), 3.8-3.6 (m, 2H), 3.5 (m, 2H), 2.1-1.9 (m, 2H), 1.8-1.5 (m, 2H).
