Procedure

To a stirred solution of (E)-(2-chloro-4-(3-(3,4,5-trichlorophenyl)-4,4,4-trifluorobut-1-en-1-yl)phenyl)methanamine (0.2 g, 0.5 mmol) in CH2Cl2 (5 mL) at 0° C. were added TEA (0.141 mL, 1 mmol) and N,N-dimethylcarbamoyl chloride (0.08 g, 0.075 mmol), and the reaction mixture was stirred for 1 h at 0° C. The reaction mixture was diluted with CH2Cl2. The organic layer was washed with H2O and brine, dried over Na2SO4, and concentrated under reduced pressure. Purification by column chromatography (SiO2, 100-200 mesh; 30-50% EtOAc in hexane) afforded the title compound as a solid (0.15 g, 60%): 1H NMR (400 MHz, CDCl3) δ 7.39 (m, 4H), 7.28 (m, 1H), 6.54 (d, J=16.0 Hz, 1H), 6.34 (dd, J=16.0, 8.0 Hz, 1H), 4.97 (br s, 1H), 4.38 (d, J=6.0 Hz, 2H), 4.10 (m, 1H), 2.9 (s, 3H), 2.7 (s, 3H); ESIMS m/z 497 ([M−H]−); IR (thin film) 3350, 1705, 1114, 808 cm−1.
