Versuchsvorschrift

Using a Perrier modification, Perrier, Chem. Ber., Vol. 33, pp. 819 et seq. (1900), and Perrier, Bull. Soc. Chim. France, pp. 859 et seq. (1904), 1,3-dimethoxybenzene (138.0 g) (which may be obtained from Aldrich Chemical Company, Inc., Milwaukee, Wis.) is reacted with acetyl chloride (72.0 g), methylene chloride (500 ml), and aluminum chloride (145 0 g) to provide 2',4'-dimethoxy-acetophenone, which may then be purified using standard vacuum fractional distillation.
