Procedure

To a solution of 5 g (29.37 mmols) of diphenylether and 15.23 g (64.61 mmols) of alpha-bromoisobutrylbromide (purity 97.5% by weight) in 50 ml of dichloromethane in about 30′ 8.61 g (64.61 mmols) of aluminum trichloride were added, maintaining the temperature between 0° and 5° C. After 1.5 h the reaction mixture was poured in a mixture of 200 ml of water and ice and 4 ml of 37% HCl. The organic phase was separated and washed with brine, dried on sodium sulphate, and filtered, A sample obtained after evaporation of the solvent was analysed.
