342 g of 1,1-dimethylpentyl chloride were added dropwise to a mixture of 428 g of 3-phenyl-2-methylpropyl chloride and 40.6 g of FeCl3 at 35° C., and the mixture was stirred for 7 hours at 50° C. and for 14 hours at room temperature. The crude product was dissolved in 2 l of CHCl3, and the solution was washed with dilute HCl and water, dried over Na2CO3 and concentrated. Distillation of the residue gave 500 g of (XII) of boiling point 126°-132° C./0.2 mbar.
