To a solution of 1-(2,6-dichlorophenyl)-6-oxo-1,6-dihydro-3-pyridinecarboxylic acid (56 mg) in DMF (0.76 mL) were added 3-amino-N-cyclopropyl-4-methylbenzamide (45 mg), WSC—HCl (57 mg), HOBt (35 mg) and Et3N (27 mg), and the mixture was stirred under a nitrogen atmosphere at room temperature for 16 hr. The reaction mixture was diluted with EtOAc (2 mL), washed with water (4 mL×2) and brine successively, dried over MgSO4, filtered and evaporated in vacuo. The residue was purified by preparative thin layer chromatography eluting with 10% MeOH in CH2Cl2 to give N-{5-[(cyclopropylamino)carbonyl]-2-methylphenyl}-1-(2,6-dichlorophenyl)-6-oxo-1,6-dihydro-3-pyridinecarboxamide (60 mg).
