Procedure
The above 3'-bromo-4'-hydroxy-4-acetylbiphenyl (200 g) was treated with 1.2 times equivalents of R 1-methylheptyl p-toluenesulfonate and potassium hydroxide in 97% ethanol (1 l) for 6 hours under reflux. The reaction mixture was worked up in a usual way to obtain crude oily 3'-bromo-4'-(1-methylheptyloxy)-4-acetylbiphenyl (163 g).
