Procedure
A solution of 4-(4′-hydroxyphenyl)benzoic acid (25.6 g) in 10% hydrochloric acid-methanol was stirred for 3 days at room temperature. Then the solvent was evaporated in vacuo and the residue was triturated with toluene-ethyl acetate (20:1) to afford methyl 4-(4′-hydroxyphenyl)benzoate (26.5 g).
