Procedure

The procedure is as in Example 2 for the preparation of ethyl (phenylthio)acetate, starting with n-butylmercaptan (10.7 cc), a 2M ethanolic solution of sodium ethylate (50 cc) and ethyl bromoacetate (16.7 g) in ethanol (100 cc). Ethyl (n-butylthio)acetate (15.4 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
