Procedure

HBr is passed, at 0°, into a solution in 50 ml of CH2Cl2 of 2.42 g of 1-propyl-4-p-propylphenylcyclohexene (obtainable by reacting 4-p-propylphenylcyclohexanone with C3H7MgBr, hydrolysing the product to give 1-propyl-4-p-propylphenylcyclohexan-1-ol and dehydrating the latter), the mixture is allowed to stand overnight and is worked up in the customary manner to give r-1-bromo-1-propyl-cis-4-p-propylphenylcyclohexane.
