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 Et3N (0.141 mL, 1 mmol) and methyl 2-chloro-2-oxoacetate (0.09 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 H2O and brine, dried over Na2SO4, and concentrated under reduced pressure. Purification by column chromatography (SiO2, 100-200 mesh; 20% EtOAc in hexane) afforded the title compound as a solid (0.12 g, 50%): 1H NMR (400 MHz, CDCl3) δ 7.48 (m, 1H). 7.43 (m, 3H), 7.38 (m, 1H), 7.23 (s, 1H), 6.55 (d, J=16.0 Hz, 1H), 6.36 (dd, J=16.0, 8.0 Hz, 1H), 4.60 (d, J=4.4 Hz, 2H), 4.18 (m, 1H), 3.85 (s, 3H); ESIMS m/z 512.22 ([M−H]−); IR (thin film) 1740, 1701, 1114, 808 cm−1.
