The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with 1-chloromethyl-4-trifluoromethylbenzene (9.8 g), a 2M ethanolic solution of sodium ethylate (25 cc) and ethyl 2-mercaptoacetate (6.1 g) in ethanol (120 cc). Ethyl (4-trifluoromethylbenzylthio)acetate (12.2 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
