실험 절차

To a stirred solution of 8-bromo-5-isoquinolinecarboxaldehyde oxime (i.e. the product from Step B) (70 mg, 0.28 mmol) in N,N-dimethylformamide (2.0 mL) was added N-chlorosuccinimide (64 g, 0.48 mmol). The reaction mixture was stirred for 0.5 h at room temperature, and then a solution of 1,3-dichloro-5-[1-(trifluoromethyl)ethenyl]benzene (135 mg, 0.56 mmol) (i.e. the product from Example 1, Step B) and triethylamine (0.12 mL, 0.86 mmol) in N,N-dimethylformamide (1.5 mL) was added. After stirring for an 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 silica gel column chromatography using hexanes/ethyl acetate as eluent to afford the title compound (20 mg) contaminated with some impurity.
