実験手順
When an equivalent amount of o-hydroxyacetophenone is substituted in the procedure of Example 11 for salicylaldehyde and α-bromo-p-methoxyacetophenone is substituted for α-bromo-p-chloroacetophenone, there is ultimately obtained 3-methyl-2-(4-methoxybenzoyl)benzofuran. Demethylation of 3-methyl-2-(4-methoxybenzoyl)-benzofuran as described above gives 3-methyl-2-(4-hydroxybenzoyl)benzofuran.
