Synthesis of 1-Bromonaphthalene

To a reflux apparatus add 43 g of naphthalene and 14 mL of carbon tetrachloride, heat the mixture with stirring to suspend the compound then start and fast addition of 18.3 mL of bromine dissolved in 3 mL of carbon tetrachloride and reflux for 2h. After the reflux, the solution is distilled at 140°C to remove the solvent and the HBr gasses then the solution is refluxed with 5 g of NaOH and then vacuum (10 mmHg) fraction distilled by collecting the fraction of 133-135°C.
