Procedure

To a stirred solution of (E)-2-bromo-N-(piperidin-4-yl)-4-(4,4,4-trifluoro-3-(3,4,5-trichlorophenyl)but-1-enyl)benzamide (0.1 g, 0.16 mmol) in CH2Cl2 (10.0 mL) was added TEA (0.046 mL, 0.35 mmol) and stirred for 10 min. Then acetyl chloride (0.014, 0.18 mmol) was added and stirred for 16 h at ambient temperature. The reaction mixture was diluted with CH2Cl2 and washed with saturated NaHCO3 solution and brine solution. The combined CH2Cl2 layer was dried over Na2SO4 and concentrated under reduced pressure to afford crude compound. The crude compound was washed with 5% diethyl ether/n-pentane to afford the title compound as a white solid (0.054 g, 50%).
