Procedure

Starting from 2-[3-bromo-5-(4-methoxyphenyl)-4-methylthien-2-yl]-1,3-dioxolane (1.5 g, 4.2 mmol, made in Example 1, Step 1) and substituting 3-formyl-4-methoxyphenylboronic acid (0.83 g, 4.6 mmol) in place of 3-methoxyphenylboronic acid (Step 2), the title compound (0.26 g, 35%, m.p. 228-30° C.) was synthesized in essentially the same manner as described in Example 1, Steps 2-4.
