The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with 3-bromomethyltoluene (15 g), a 2M ethanolic solution of sodium ethylate (44.5 cc) and ethyl 2-mercaptoacetate (9.7 g) in ethanol (100 cc). Ethyl (3-methylbenzylthio)acetate (14.4 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
