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

Procedure

When 2-(4'-chlorophenyl)benzofuran was acylated with anisoyl chloride was described in the procedure of Example 10 and the resulting 2-(4'-chlorophenyl)-3-(4'-methoxybenzoyl)benzofuran was demethylated with pyridine hydrochloride as previously described, 2-(4'-chlorophenyl)-3-(4'-hydroxybenzoyl)benzofuran was obtained.
