In the same manner as that of Example 2, 4,5-diisopropylfuran-2-carboxylic acid (90 mg, 0.459 mmol) was condensed with methyl 3-[4-aminophenyl]propionate, and the resultant was purified by silica gel chromatography [benzene-ethyl acetate (14:1)] to obtain methyl 3-[4-[(4,5-diisopropylfuran-2-carbonyl)amino]phenyl]propionate (138 mg, 84%) as colorless needles.
