The crude product of 4-pentyloxyphthalic acid was dissolved in acetic acid (20 ml), and tyramine hydrochloride (2.74 g, 20 mmol) was added. The mixture was stirred at 96° C. for 4 hours, and concentrated under reduced pressure. The obtained residue was purified by column chromatography on silica gel (hexane/ethyl acetate=6/1) to give N-2-(4-hydroxyphenyl)ethyl-4-pentyloxyphthalimide (2.6 g, 9.4 mmol, 88%) as colorless crystals.
