Participants

Reaction Steps

A solution of 8-(3,4-dichlorophenyl)octan-1-ol (0.66 g) in 48% hydrobromic acid (7 ml) was stirred under reflux for 2 h. Water (20 ml) and diethyl ether (20 ml) were added. The organic layer was separated and the aqueous layer reextracted with diethyl ether (10 ml). The combined organic extracts were washed with water (10 ml), sodium hydrogen carbonate solution (10 ml) and brine (10 ml) and dried over magnesium sulfate. The solution was treated with charcoal, filtered and evaporated under reduced pressure to give 1-bromo-8-(3,4-dichlorophenyl)octane (0.74 g). 1H-NMR (CDCl3) δ 1.2-1.8 (12H, m), 2.55 (2H, t), 3.41 (2H, t), 7.00 (1H, dd), 7.25 (1H, dd) and 7.33 (1H, d).
