Procedure

A mixed solution of 4-(4′-hydroxyphenyl)benzoic acid (10.0 g, 4.67 mmol), iodomethane (19.9 g, 14.0 mmol) and N,N-dimethylformamide (80 ml) was stirred at 60° C. for 3 hours. To the obtained mixture was added ethyl acetate (200 ml) and water (150 ml), the mixture was stirred and the organic layer was separated. The organic layer was washed with 5% aqueous potassium hydrogen sulfate and water, and dried over sodium sulfate anhydride. The solvent was concentrated under reduced pressure and the object compound (10.5 g) was obtained from the residue as colorless crystals. Melting point: 177-178° C.
