Versuchsvorschrift

To a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (0.102 g, 0.00042 mol) in DMF (1 mL) was added DIPEA (0.245 g, 0.00190 mol), HOBt (0.056 g, 0.000418 mol) and EDCI.HCl (0.145 g, 0.00076 mol) at ambient temperature. After 2 minutes piperidin-4-yl-o-tolyl-amine dihydrochloride (0.1 g, 0.00038 mol) was added and the resulting mixture was stirred for 16 hours. The reaction mixture was then diluted with cold water. The resulting precipitate was isolated by filtration and dried to afford 0.15 g (94% of 5-phenyl-1H-pyrazole-3-carboxylic acid [2-oxo-2-(4-o-tolylamino-piperidin-1-yl)-ethyl]-amide.
