実験手順

Following the procedures of Example 1, but substituting 2-iodoanisole for 2-isopropylanisole, methyl 3,5-dibromo-4-mercaptophenylacetate (1 g) was reacted with 2-iodoanisole (0.7 g) to yield the thioether, methyl 3,5-dibromo-4-(3-iodo-4-methoxyphenylthio)phenylacetate (1.4 g) which in turn was oxidized to methyl 3,5-dibromo-4-(3-iodo-4-methoxyphenylsulfonyl)phenylacetate, MP: 127°-129° C. The acetate was saponified to the acid, 3,5-dibromo-4-(3-iodo-4-methoxyphenylsulfonyl)phenylacetic acid, MP: 158°-162° C.
