실험 절차

50.8 g (0.27 mol) of 2,5-dichloro-2,5-dimethylhexane, 30 g (0.27 mol) of 2-methylphenol and 500 ml of dichloromethane were introduced into a three-necked flask. 14.8 g (0.11 mol) of aluminum chloride were added in small amounts at 0° C. and the entire contents were stirred at room temperature for twelve hours. The reaction medium was poured into ice-cold water, extracted with dichloromethane, the organic phase decanted off, washed with sodium bicarbonate, dried over magnesium sulfate and evaporated.
