Versuchsvorschrift

The procedure is as in Example 2 for the preparation of ethyl (phenylthio)acetate starting with ethyl bromoacetate (11.7 g), a 2M ethanolic solution of sodium ethylate (35 cc) and 4-methoxythiophenol (10 g). Ethyl (4-methoxyphenylthio)acetate (13.6 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
