Procedure

To a stirred solution of (E)-O-(4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)phenyl)hydroxylamine (0.15 g, 0.38 mmol) in CH2Cl2 (5 mL) was added EDC.HCl (0.109 g, 0.569 mmol), HOBt.H2O (0.087 g, 0.569 mmol), DIPEA (0.097 g, 0.758 mmol) and cyclopropanecarboxylic acid (0.049 g, 0.569 mmol). The resultant reaction mixture was stirred at ambient temperature for 18 h. The reaction mixture was diluted with water and extracted with CHCl3 (35 mL) The combined CHCl3 layer was washed with brine, dried over Na2SO4 and concentrated under reduced pressure. Purification by flash column chromatography (SiO2; 20% EtOAc in hexane) afforded the title compound as a brown liquid (0.06 g, 34%): 1H NMR (400 MHz, CDCl3) δ 7.40 (s, 2H), 7.18 (s, 1H), 7.08 (s, 1H), 6.85 (m, 1H), 6.45 (m, 1H), 6.65 (m, 1H), 6.20 (m, 1H), 5.55 (s, 1H), 4.08 (m, 1H), 1.90 (m, 1H), 1.30-1.10 (m, 4H); ESIMS m/z 464.87 ([M−H]−).
