실험 절차
The procedure is as in Example 4 for the preparation of α-methylthioacetophenone, starting with a stirred solution of 4-(2-chloroacetyl)pyrocatechol (18.6 g) in methanol (200 cc). Sodium methanethiolate (7 g) is added in the course of 15 minutes at a temperature in the region of 20° C., and the mixture is left with stirring for 3 hours at the same temperature. 4-[2-(Methylthio)acetyl]pyrocatechol (14.5 g), m.p. 107° C., is thereby obtained.
