実験手順

To a stirred solution of tert-butyl 5-vinyl-1H-indole-1-carboxylate (0.65 g, 2.67 mmol), in 1,2-dichlorobenzene (10.0 mL) was added 5-(1-bromo-2,2,2-trifluoroethyl)-1,3-dichloro-2-fluorobenzene (1.74 g, 5.37 mmol), CuCl (53 mg, 0.537 mmol) and 2,2-bipyridyl (167 mg, 1.07 mmol). The resultant reaction mixture was degassed with argon for 30 min and heated to 150° C. for 2 h. The reaction mixture was cooled to ambient temperature and filtered, and the filtrate concentrated under reduced pressure. The crude compound was purified by column chromatography (SiO2, 100-200 mesh; 2% EtOAc/petroleum ether) to afford the title compound as a light brown gummy material (0.25 g, 10%): 1H NMR (400 MHz, CDCl3) δ 8.20 (d, J=8.0 Hz, 1H), 7.60 (m, 2H), 7.39 (m, 3H), 6.69 (d, J=16.0 Hz, 1H), 6.55 (d, J=10.5 Hz, 1H), 6.36 (dd, J=16.0, 8.0 Hz, 1H), 4.10 (m, 1H), 1.65 (s, 9H); ESIMS m/z 485.91 ([M−H]−); IR (thin film) 1165, 854 cm−1.
