Versuchsvorschrift

45.3 Ml of p-xylene and 8.2 g of anhydrous aluminum chloride are added to the solution of 2-acetyl-5-bromo-6-methoxynaphthalene obtained as in example 1a), while keeping the temperature at -10° C. The reaction mixture is kept for 16 hours under stirring at room temperature and then it is worked as in example 1 obtaining 42.8 g of product with a yield equal to 87.3% calculated on the basis of the starting material 1-bromo-2-methoxynaphthalene.
