Procedure
In the same manner as that of Example 2, 4,5-diisopropylfuran-2-carboxylic acid (80 mg, 0.408 mmol) and methyl 2-fluoro-4-aminobenzoate (125 mg, 0.739 mmol) were condensed, the reaction mixture was treated in a conventional manner, and then the residue was purified by silica gel chromatography [hexane-ethyl acetate (40:1)] and recrystallized to obtain methyl 2-fluoro-4-[(4,5-diisopropylfuran-2-carbonyl)amino]benzoate (95 mg, 67%) as colorless prisms.
