3-(Trifluoromethoxy)phenylboronic Acid (contains varying amounts of Anhydride) → Methyl 3-[3-(trifluoromethoxy)phenyl]-1-benzofuran-5-carboxylate

Participants

Reaction Steps

In the same manner as in Reference Example 19 and using methyl 3-bromo-1-benzofuran-5-carboxylate instead of methyl 3-iodoimidazo[1,2-a]pyridine-6-carboxylate and [3-(trifluoromethoxy)phenyl]boronic acid instead of (4-methoxyphenyl)boronic acid, the title compound (yield 80%) was obtained as colorless crystals.
