Yield:-
Reaction Conditions:
with iron(III) chloride in ethylbenzene;water;
Steps:
5 Preparation of 1,1,4,4-Tetramethyl-6-Ethyl-1,2,3,4-Tetrahydronaphthalene-7-ol Formate Ester
Specifically, a mixture of 93 g of ethylbenzene and 2 g of anhydrous ferric chloride is cooled to -5° C., and to it is added a solution of 61 g of 2,5-dichloro-2,5-dimethylhexane in 83 g of ethylbenzene during 30 min., maintaining the temperature at -5° C. and agitating continuously. The solution is quenched in water, washed to neutrality and distilled to yield, in addition to the excess of ethylbenzene, 1,1,4,4-tetramethyl-6-ethyl-1,2,3,4-tetrahydronaphthalene.
