Yield:565228-31-1 97%
Reaction Conditions:
with acetic acid at 60;
Steps:
2.1.4 5,8-Dibromo-2,3-bis(3-(octyloxy)phenyl)quinoxaline (9)
A mixture of compound 2 (2.28 g, 8.58 mmol) and compound 5 (4 g, 8.58 mmol) were added into the acetic acid (70 ml), the mixture was briefly warmed to 60 °C, and then the solution was stirred at room temperature for another 2 h. The precipitate was collected by filtration, washed with ethanol, and dried to afford 5,8-dibromo-2,3-bis(3-(octyloxy)phenyl)quinoxaline 9 (5.69 g) as a white solide in yield 97%. 1H NMR (CDCl3, 500 MHz) δ (ppm): 7.91(s,2H), 7.23(d,4H, J = 10 Hz), 7.18(d,2H, J = 10 Hz), 6.94(d,2H, J = 10 Hz), 3.87(t,4H, J = 6.5 Hz), 1.75(q,4H), 1.25-1.52(m,20H), 0.91(t,6H, J = 5.5 Hz). 13C NMR (CDCl3, 500 MHz) δ (ppm): 159.07, 154.05, 139.31, 139.14,133.09, 129.33, 123.72, 122.56, 116.57, 115.77, 68.12, 31.85, 29.36, 29.29, 29.13, 26.04, 22.70, 14.13.
