Procedure

To a stirred solution of [(5-phenyl-1H-pyrazole-3-carbonyl)-amino]-acetic acid (0.097 g, 0.00040 mol) in DMF (1 mL) was added DIPEA (0.233 g, 0.00180 mol), HOBt (0.053 g, 0.00040 mol) and EDCI.HCl (0.138 g, 0.0007214 mol) at ambient temperature. After 2 minutes (2,4-dimethyl-phenyl)-piperidin-4-yl-amine dihydrochloride (0.1 g, 0.00036 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 0.12 g (77%) of 5-phenyl-1H-pyrazole-3-carboxylic acid {2-[4-(2,4-dimethyl-phenylamino)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 432.23 (M+1)+, 97.64%, 1H NMR (DMSO-d6): δ 8.1 (s, 1H), 7.8 (d, 2H), 7.5 (t, 2H), 7.4 (d, 1H), 7.1 (s, 1H), 6.6 (d, 1H), 4.3 (m, 2H), 4.1 (t, 2H), 3.9 (d, 1H), 3.5 (bs, 1H), 3.2 (t, 1H), 2.8 (t, 1H), 2.2 (s, 3H), 2.1 (s, 3H), 1.9 (t, 2H), 1.5 (m, 1H), 1.3 (m, 1H).
