Procedure

Starting from 2-[3-bromo-5-(4-methoxyphenyl)-4-methylthien-2-yl]-1,3-dioxolane (1.1 g, 3.0 mmol, made in Example 1, Step 1) and substituting 4-methoxy-2-methylphenylboronic acid (0.55 g, 3.3 mmol) in place of 3-methoxyphenylboronic acid (Step 2), the title compound (0.56 g, 90%, m.p. 244-47° C.) was synthesized in essentially the same manner as described in Example 1, Steps 2-4.
