Versuchsvorschrift

The procedure is as in Example 29 for the preparation of ethyl (4-methylbenzylthio)acetate, starting with 2-bromomethyltoluene (10 g), a 2M ethanolic solution of sodium ethylate (30 cc) and ethyl 2-mercaptoacetate (6.5 g), in ethanol (100 cc). Ethyl (2-methylbenzylthio)acetate (8.9 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
