実験手順

A solution of 2-fluoro-4-cyanobenzoic acid (1 g, 6.06 mmol) in thionyl chloride (5 ml) was refluxed for 2 hr. After concentration, the residue was dissolved in dichloromethane (5 ml). And a solution of the compound of (2-amino-5-chlorophenyl)-N-(5-chloro(2-pyridyl))carboxamide (1.2 g, 4.25 mmol) in dichloromethane (10 ml) and pyridine (1.47 ml, 18.18 mmol) were added. The mixture was stirred at r.t. overnight. The precipitate was filtered and washed with a little amount of dichloromethane to give N-{4-chloro-2-[N-(5-chloro(2-pyridyl))carbamoyl]phenyl}(2-fluoro-4-cyanophenyl)carboxamide (2.03 g, 78%). MS found for C20H11Cl2FN4O2 M+=429, (M+2)+=431.
