Versuchsvorschrift

51 Ml of mesitylene 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 3 hours under stirring at 0° C. and then it is worked as in example 1 obtaining 43.2 g of product with a yield equal to 88.2% calculated on the basis of the starting material 1-bromo-2-methoxynaphthalene.
