Procedure
Starting from 2-(3-bromo-5-iodo-4-methylthien-2-yl)-1,3-dioxolane (2.3 g, 6.1 mmol) and 3-fluoro-4-methoxyphenylboronic acid (1.6 g, 9.4 mmol) in place of 4-methoxyphenylboronic acid (Step 1), and substituting 4-methoxyphenylboronic acid in place of 3-methoxyphenylboronic acid (Step 2), the title compound (0.42 g, 86%, m.p. 227-29° C.) was synthesized in essentially the same manner as described in Example 1.
