Versuchsvorschrift

A mixture of 11.6 g. (0.052 mol.) of 3,5-diethyl-4-methoxybenzoic acid methyl ester and 3.5 g. (0.09 mol.) of sodium hydroxide in 150 ml. of water is refluxed for 2 hours. The reaction mixture is cooled and acidified with 10% aqueous hydrochloric acid to give 3,5-diethyl-4-methoxybenzoic acid. The acid is refluxed with thionyl chloride as described in the procedure of Example 27 to give 3,5-diethyl-4-methoxybenzoyl chloride.
