8. Under anhydrous conditions, 4.8 mL of 1-bromo-3,5-dimethylbenzene (dens. 1.36 g/mL) is treated with 0.90 g of magnesium in 25 mL of diethyl ether. After the initial reaction, the ether solution is poured over 8.5 grams of dry ice (carbon dioxide). The mixture is then treated with 50 mL 1M aqueous HCl. The resulting biphasic mixture is transferred to a separatory funnel and the aqueous layer is removed. The organic layer that remains in the separatory funnel is then treated with 20 mL 3M aqueous NaOH. After shaking the separatory funnel and allowing the layers to separate, the aqueous layer is removed and treated with aqueous 6M HCl until a precipitate forms and the pH of the solution acidic by pH paper. The precipitate is isolated by vacuum filtration and allowed to dry resulting in 3.73 g of a white solid (m. p. 171.2 – 173.4 °C).
