The reaction mixture was stirred for 1 h at room temperature, and then a solution of 1,3-dichloro-5-[1-(trifluoromethyl)ethenyl]benzene (i.e. the product from Example 1, Step B) (1.96 g, 8.1 mmol) and triethylamine (2.86 mL, 20.4 mmol) in N,N-dimethylformamide (7.0 mL) was added. After stirring for additional 12 h at room temperature, the reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was washed with brine, dried (Na2SO4), and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using hexanes/ethyl acetate as eluent to afford the title compound as a white solid (2.0 g, 61% yield).
