Procedure
Acylation of 2-(3-trifluoromethylbenzyl)benzofuran with 4-methoxybenzenesulfonyl chloride as described in the procedure described above followed by demethylation of the 3-(4-methoxyphenylsulfonyl)-2-(3-trifluoromethylbenzyl)benzofuran thus formed also as described above gives 3-(4-hydroxyphenylsulfonyl)-2-(3-trifluoromethylbenzyl)benzofuran.
