The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with 1-bromomethyl-4-isopropylbenzene (15 g), a 2M ethanolic solution of sodium ethylate (49 cc) and ethyl 2-mercaptoacetate (9.8 g) in ethanol (150 cc). Ethyl (4-isopropylbenzylthio)acetate (17.9 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
