Reaction Steps

It is easy to synthesis the following compound in the same manner as in Example 1 except that 2-(benzofuran-2-yl)-5-bromopyridine was synthesized from 2,5-dibromopyridine (made by Tokyo Kasei Kogyo K.K.) and 2-benzofuranboronic acid (made by Aldrich Co.) and is reacted with 1-naphthylboronic acid (made by Tokyo Kasei Kogyo) to obtain 2-(benzofuran-2-yl)-5-(naphthalene-1-yl)pyridine, which is used instead of 2-(5-trifluoromethylpyridine-2-yl)benzofuran.
