71% | A 250 ml three-necked flask equipped with a condenser was charged with 3.7 g (10 mmol) of <strong>[707-34-6]1,3,5-tribromoadamantane</strong>, 16.0 g of 1,3-dibromo-2-methoxybenzene (60.0 mmol) and30 ml of 1,2-dichloroethane,Condenser duct from the upper end connected to an inverted funnel 30% NaOH aqueous solution,To absorb the HBr produced by the reaction.At 0 ice water bath,1.0 g (ie, 4.0 mmol) of AlBr3 was added to the reaction system,Continue stirring in the ice water bath for half an hour,Then gradually returned to room temperature,The reaction system was heated in an oil bath to 60 C for 5 hours,The reaction solution was cooled to room temperature,Pour into 100 mL of acidic ice water and stir for 1 h.After the ice has completely melted, 100 ml of methylene chloride is added to the mixture for extraction. The organic layer is washed with water until neutral, washed with saturated brine, dried over anhydrous sodium sulfate, filtered and the filtrate is concentrated. The mixture is then recrystallized from a mixed solution of ethyl acetate and methanol ,6.58 g of a white solid was obtained in a yield of 71%. |
