Reaction Conditions

Reaction Steps

1,12-Dibromododecane (mmol) was added to a solution (30 mL) of dry pyridine, and the solution heated for 24 hours at 65° C. The resulting precipitate was filtered, and the product washed five times with dry diethyl ether. The resulting white solid was isolated in a 93% yield. 1H NMR (300 MHz, DMSO-D6) δ 9.15 (2H, d, C2&C6-H), 8.62 (1H, t, C4-H), 8.19 (2H, t, C3&C5-H), 4.61 (2H, t, C′1-CH2), 1.88 (2H, m, C′2-CH2), 1.22 (8H, m, C′3-6-CH2); 13C NMR (75 MHz, DMSO-D6) δ 145.3, 144.6, 127.9, 60.7, 30.8, 28.9, 28.8, 28.5, 25.4.
