Reaction Conditions

Reaction Steps

1,9-Dibromononane (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 clear liquid was isolated in a 87% yield. 1H NMR (300 MHz, DMSO-D6) δ 9.17 (2H, d, C2&C6-H), 8.61 (1H, t, C4-H), 8.18 (2H, t, C3&C5-H), 4.63 (2H, t, C′1-CH2), 1.89 (2H, m, C′2-CH2), 1.22 (5H, m, C′3-5-CH2); 13C NMR (75 MHz, DMSO-D6) δ 145.3, 144.5, 127.9, 60.5, 30.7, 28.4, 28.2, 25.3.
