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 ethyl isothiocyanate (0.053 g, 0.75 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 water 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 (0.14 g, 60%): mp 88-91° C.; 1H NMR (400 MHz, CDCl3) δ 7.49 (d, J=8 Hz, 1H), 7.41 (d, J=7.2 Hz, 2H), 7.26 (m, 2H), 6.50 (d, J=16 Hz, 1H), 6.35 (dd, J=16.0, 8.0 Hz, 1H), 6.0 (br s, 1H), 5.73 (br s, 1H), 4.80 (br s, 2H), 4.09 (m, 1H), 1.23 (m, 3H); ESIMS m/z 515.01 ([M+H]+).
