The procedure is as in Example 33 for the preparation of ethyl (3-phenoxyphenyl)acetate, starting with (3-benzoylphenyl)acetic acid (16.6 g) and 36N aqueous sulphuric acid solution (2 cc) in ethanol (200 cc). Ethyl (3-benzoylphenyl)acetate (16.8 g) is obtained in the form of a brown oil, and is used in the crude state in the subsequent syntheses.
