Reaction Conditions

Reaction Steps

1,5-Diiodopentane (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 yellow solid was isolated in a 90% yield. 1H NMR (300 MHz, DMSO-D6) δ 9.14 (2H, d, C2&C6-H), 8.62 (1H, t, C4-H), 8.19 (2H, t, C3&C5-H), 4.62 (2H, t, C′1-CH2), 1.92 (2H, m, C′2-CH2), 1.25 (1H, m, C′3-CH2).
