Product 1

HCID 139587354-[2,3-Dichloro-4-(2-methylenevaleryl)phenoxy]butyric acid

Procedure

By conducting the reaction as described in Example 2, Step B, except that an equimolar amount of 4-(2,3-dichloro-4-valerylphenoxy)butyric acid was substituted for the 4-(2,3-dichloro-4-butyrylphenoxy)butyric acid, there was obtained 4-[2,3-dichloro-4-(2-methylenevaleryl)phenoxy]butyric acid, m.p. 85°-87° C.
