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 to 150 mL of methylene chloride followed by the addition of 11.4 g (55.0 mmol) of dicyclohexylcarbodiimide while stirring in the presence of argon. After stirring for 6 hours in the presence of argon, the mixture was filtered followed by concentrating the filtrate. The residue was purified by silica gel column chromatography to obtain 18.7 g of a white solid.
