71% | n-BuLi (2.5 M in hexanes, 1.9 mL, 4.6 mmol) was added drop-wise to a solution of <strong>[864550-95-8]2-bromo-9-hexylcarbazole</strong> (1.3 g, 3.8 mmol) in dry THF (25 mL) at -78 C over 0.5 h. The reaction was stirred at -78 C for 2 h, then 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (7.5 mmol, 1.5 mL) was added and the reaction was allowed stir at rt for 18 h. The milky solution was then poured onto iced H2O and extracted using diethylether. The organic layer was then washed with saturated NaCl and dried over Na2SO4. Solvents were removed in vacuo and the yellow oily residue was recrystallized from ethanol to give white crystals (1.01 g, 71%, 2.7 mmol). Mp=86 C; 1H NMR (400 MHz, CDCl3): δH=0.92 (t, 3JH-H=13.8 Hz, 3H, CH3), 1.31-1.34 (m, 6H, CH2), 1.45 (s, 12H, CH3), 1.86-1.92 (m, 2H, CH2), 4.37 (t, 3JH-H=14.6 Hz, 2H, CH2), 7.25 (t, 3JH-H=14.5 Hz, 1H, carbazole-H), 7.45 (d, 3JH-H=8.2 Hz, 1H, carbazole-H), 7.51 (t, 3JH-H=15.1 Hz, 1H, carbazole-H), 7.72 (d, 1H, 3JH-H=7.8 Hz, 1H, carbazole-H), 7.93 (s, 1H, carbazole-H), 8.13 (d, 3JH-H=3.0 Hz, 1H, carbazole-H), 8.15 (d, 3JH-H=3.0 Hz, 1H, carbazole-H) ppm; 13C NMR (100 MHz, CDCl3): δC=13.6, 22.1, 24.5, 26.5, 28.6, 31.2, 42.5, 83.3, 108.4, 114.6, 118.2, 119.2, 120.1, 124.5, 125.7, 139.5, 140.5 ppm; FT-IR (ATR): ν=2961, 2928, 2859, 1624, 1560, 1497, 1477, 1436, 1363, 1334, 1270, 1255, 1236, 1141, 1081, 966, 927, 854, 748, 732, 687 cm-1; HRMS (ESI+) [C24H32NO2+H]: calcd 378.2604, found 378.2606. |

Ca. 94% | To a 250 mL three-necked flask, 2-bromocarbazole (6.0 g, 24.38 mmol), sodium hydroxide solution (50%) 4 ml, tetrabutylammonium bromide (0.4 g, 1.24 mmol), and the temperature was stirred for 5 min at room temperature. Bromine hexane (8.045 g, 48 mmol) was added dropwise with a syringe.After 12 h of reaction, the eluent was purified by column chromatography to petroleum ether to afford product 1a as an oil, which, after vacuum drying, weighed 7.57 g (yield about 94%). |

72% | In N,N-dimethyl-formamide; at 155℃;Inert atmosphere; | Compound 1a (7.57 g, 22.92 mmol) was added to a 250 mL three-neck reaction flask, and CuCN (4.4 g, 49.12 mmol) was purged with nitrogen for 3 times, and then 20 mL of DMF was added by a syringe, and the temperature was raised to After 155 C, the magnetic stirrer was turned on and stirred overnight. After the reaction was stopped, the mixture was extracted with ethyl acetate and deionized water for 2-3 times, dried over anhydrous magnesium sulfate, filtered, and purified by column chromatography. Petroleum ether = 1 : 4) gave 4.57 g (yield: 72%) as a white solid. |
