Versuchsvorschrift

The procedure is as in Example 20 for the preparation of ethyl n-decanoate, starting with (phenylthio)acetic acid (20 g) and 36N aqueous sulphuric acid solution (0.32 cc) in cyclohexanol (100 cc). After purification by chromatography on a silica column with a mixture of cyclohexane and ethyl acetate (70:30 by volume) as eluent, cyclohexyl (phenylthio)acetate (29 g) is obtained, and is used in the crude state in the subsequent phases.
