Procedure

The procedure is as in Example 4 for the preparation of α-methylthioacetophenone, starting with 2-(2-bromoacetyl)naphthalene (12.5 g) and sodium methanethiolate (3.5 g) in ethanol (100 cc). 2-[2-(Methylthio)acetyl]naphthalene (8 g) is thereby obtained, and is used in the crude state in the subsequent syntheses.
