In the same manner as that of Example 2, 4,5-diisopropylfuran-2-carboxylic acid (60 mg, 0.306 mmol) was condensed with ethyl 4-aminophenylacetate, and the resultant was purified by silica gel chromatography [hexane-ethyl acetate (4:1)] to obtain ethyl 4-[(4,5-diisopropylfuran-2-carbonyl)amino]phenylacetate (94 mg, 86%) as colorless needles.
