Procedure

To a stirred solution of [(6-phenylamino-pyridine-3-carbonyl)-amino]-acetic acid (0.035 g, 0.00013 mol) in DMF (1 mL) was added DIPEA (0.05 g, 0.00039 mol), HOBt (0.0209 g, 0.00015 mol) and EDCI.HCl (0.029 g, 0.00015 mol) at ambient temperature. After 2 minutes (2-chloro-phenyl)-piperidin-4-yl-amine dihydrochloride (0.0382 g, 0.00015 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 0.051 g (85%) of N-{2-[4-(2-chloro-phenylamino)-piperidin-1-yl]-2-oxo-ethyl}-6-phenylamino-nicotinamide.
