실험 절차

To a stirred solution of 2-(4-vinylphenylamino)isoindoline-1,3-dione (0.3 g, 1.1 mmol) in 1,2-dichlorobenzene (5 mL) were added CuCl (0.022 g, 0.273 mmol), 2,2-bipyridyl (0.07 g, 0.46 mmol) and 5-(1-bromo-2,2,2-trifluoroethyl)-1,2,3-trichlorobenzene (0.77 g, 2.27 mmol). The reaction mixture was degassed with argon for 30 min and was heated at 180° C. for 2 h. The reaction mixture was then concentrated under reduced pressure, and the residue was purified by column chromatography (SiO2, 0-30% EtOAc in petroleum ether) to afford the title compound as a solid (450 mg, 75%): mp 187-189° C.; 1H NMR (400 MHz, CDCl3) δ 8.75 (s, 1H), 7.96 (m, 4H), 7.82 (s, 2H), 7.37 (d, J=8.8 Hz, 1H), 6.73 (d, J=8.4 Hz, 2H), 6.61 (m, 2H), 6.58 (m, 1H), 4.59 (m, 1H); ESIMS m/z 523.05 ([M−H]−).
