Procedure

To a stirred solution of (E)-2-chloro-4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)benzoic acid (300 mg, 0.67 mmol) and 1-amino-N-(2,2,2-trifluoroethyl)cyclopropanecarboxamide (148 mg, 0.81 mmol) in DCM/DMF (5 mL, 1:1), 2-chloro-1,3-dimethylimidazolidinium hexafluorophosphate (CIP) (92 mg, 0.33 mmol), 1-hydroxy-7-azabenzotriazole (HOAt) (48 mg, 0.33 mmol) and DMAP (5 mol %) were added, and the resulting mixture was stirred at room temperature (RT) for 4 h. The reaction mixture was poured into ice-water and extracted with EtOAc. The organic phase was dried (Na2SO4), filtered, concentrated and the residue was purified by column chromatography on silica (100-200 mesh) eluting with 30% EtOAc in petroleum ether to give the title compound as pale yellow gum (300 mg, 75%). Characterization data for this molecule is listed in Table 2.
