反応手順

7 g of aluminum chloride was added by portions to 200 ml solution of 50 g 2,5-dichloro-2,5-dimethylhexane in orthoxylene at 0° C. under stirring. After the mixture was stirred at the same temperature for 15 minutes, it was poured into ice-cold water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and then evaporated to give 60 g of 2,3,5,5,8,8-hexamethyl-5,6,7,8-tetrahydronaphthalene as a brown oil.
