Reaction Steps

To a solution of 4-chloro-3-({[1-(2,6-dichlorophenyl)-6-oxo-1,6-dihydro-3-pyridinyl]carbonyl}amino)benzoic acid (1.74 g) in DMF (17 mL) were added HATU (3.03 g), cyclopropanamine (680 mg) and iPr2NEt (3.08 g) successively at 0° C., and the mixture was stirred at room temperature for 16 hr under a nitrogen atmosphere. The mixture was partitioned between EtOAc (50 mL) and 1 M HCl (50 mL), and the precipitates produced were removed by filtration. The organic layer of the filtrate was separated and washed with 1 M HCl (50 mL), saturated aqueous NaHCO3 (50 mL×2) and brine successively, dried over MgSO4 and filtered. The filtrate was evaporated in vacuo, and the residue was triturated with a mixture of IPE and MeOH. The precipitates were collected by filtration, triturated with EtOH and collected by filtration to give N-{2-chloro-5-[(cyclopropylamino)carbonyl]phenyl}-1-(2,6-dichlorophenyl)-6-oxo-1,6-dihydro-3-pyridinecarboxamide (890 mg).
