Reaction Steps
To a solution of 14 g (103 mmol) of 3-phenyl-1-propanol and 18.2 g (123 mmol) of 2,5-dichloro-2,5-dimethylhexane in 100 mL of dichloromethane was added 15 g (113 mmol) of aluminum chloride. After the addition of aluminum chloride was complete, the reaction was heated to reflux. After 16 hours, the reaction mixture was cooled to room temperature and 100 mL of water was added, followed by 100 mL of 1N HCl. The reaction mixture was stirred for 2 hours, filtered through a Celite pad and the layers were separated. The aqueous layer was extracted with diethyl ether and the combined organic fractions were washed with brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (30% ethyl acetate/hexane) to afford 13.45 g (53%) of 2-(3-hydroxypropyl)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-naphthalene.
