Procedure

To a stirred solution of (E)-4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)-2-(trifluoromethyl)benzoyl chloride (143 mg, 0.288 mmol) in DCE (3 mL) were added 4,4,4-trifluorobutanehydrazide (45 mg, 0.29 mmol), and 4-methylmorpholine (63.4 μL, 0.577 mmol), and the resultant reaction mixture was stirred at ambient temperature for 18 h. The reaction mixture was diluted with water and extracted with EtOAc (3×30 mL). The combined EtOAc layers were washed with aqueous 1M HCl (−1×30 mL), saturated aqueous NaHCO3 (1×30 mL), and brine. The resulting organic solution was dried over Na2SO4 and concentrated under reduced pressure. Purification by automated flash column chromatography (SiO2, hexanes and EtOAc) afforded the title compound as a beige solid (78 mg, 42%): 1H NMR (400 MHz, CDCl3) δ 10.23 (s, 1H), 9.85 (s, 1H), 7.70-7.62 (m, 1H), 7.55 (dd, J=8.0, 1.6 Hz, 1H), 7.51 (d, J=8.0 Hz, 1H), 7.41 (s, 2H), 6.59 (d, J=15.9 Hz, 1H), 6.44 (dd, J=15.9, 7.8 Hz, 1H), 4.19-4.05 (m, 1H), 2.51 (dd, J=9.0, 6.6 Hz, 2H), 2.37-2.18 (m, 2H); 19F NMR (376 MHz, CDCl3) δ −59.46, −67.07, −68.59; ESIMS m/z 615 ([M−H]−).
