The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with (2-bromoethyl)benzene (20 g), a 2M ethanolic solution of sodium ethylate (25 cc) and ethyl 2-mercaptoacetate (13 g) in ethanol (150 cc). Ethyl (phenethylthio)acetate (21.7 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
