Procedure

To 150 mL of methylene chloride, 12.6 g (55.0 mmol) of 4-benzyloxy-benzoic acid, 8.2 g (50.0 mmol) of 4-pentylphenol, and 0.61 g (5.0 mmol) of 4-dimethylaminopyridine were added. Then, 11.4 g (55.0 mmol) of dicyclohexylcarbodiimide was added while stirring the mixture under argon. After being stirred for 6 hours under argon, the mixture was filtered and the filtered liquid was concentrated. The residue was purified by silica-gel column chromatography. As a result, 18.7 g of a white solid was obtained.
