Product 1

HCID 214352692-(4-Chlorophenyl)-3-(4-hydroxybenzoyl)benzofuran

Procedure

Acylation of 2-(4-chlorophenyl)benzofuran with p-anisoyl chloride followed by demethylation of the 2-(4-chlorophenyl)-3-(4-methoxybenzoyl)benzofuran thus formed by procedures described above gives 2-(4-chlorophenyl)-3-(4-hydroxybenzoyl)benzofuran.
