실험 절차

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 (2-chlorophenyl)boronic acid instead of (4-methoxyphenyl)boronic acid, the title compound (yield 92%) was obtained as colorless crystals.
