Reaction Conditions

Reaction Steps

1,9-Dibromononane (mmol) was added to a solution (30 mL) of isoquinoline, 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 purple solid was isolated in a 92% yield. 1H NMR (300 MHz, DMSO-D6) δ 10.17 (1H, d, C1-H), 8.85 (1H, d, C3-H), 8.62 (1H, d, C8-H), 8.49 (1H, d, C4-H), 8.36 (2H, d, C7-H), 8.26 (2H, t, C5-H), 8.08 (1H, t, C6-H), 4.72 (2H, t, C′1-CH2), 2.02 (2H, m, C′2-CH2), 1.78 (1H, m, C′3-CH2), 1.19-1.50 (4H, m, C′3-5-CH2).
