Versuchsvorschrift

To a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (0.04 g, 0.00014 mol) in DMF (1 mL) was added DIPEA (0.05517 g, 0.00043 mol), HOBt (0.023 g, 0.00017 mol) and EDCI.HCl (0.0326 g, 0.00017 mol) at ambient temperature. After 2 minutes 4-(2-chloro-phenylsulfanyl)-piperidine hydrochloride (0.0449 g, 0.00017 mol) was added and the resulting mixture was stirred overnight. The reaction mixture was then diluted with cold water. The resulting precipitate was isolated by filtration and dried to afford 0.054 g (84%) of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-[4-(2-chlorophenylsulfanyl)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 455.12 (M+1)+, 83.96%, 1H NMR (DMSO-d6): δ 13.65 (s, 1H), 8.1 (s, 1H), 7.8 (d, 2H), 7.5 (m, 4H), 7.38 (t, 2H), 7.24 (t, 2H), 7.15 (s, 1H), 4.2 (m, 3H), 3.85 (m, 1H), 3.65 (m, 1H), 3.25 (m, 1H), 3.0 (m, 1H), 2.0 (m, 2H), 1.56 (m, 1H), 1.4 (m, 1H).
