Procedure

In the same manner as that of Example 2, 4,5-diisopropylfuran-2-carboxylic acid (60 mg, 0.306 mmol) was condensed with ethyl 3-aminobenzoate, and the resultant was purified by silica gel chromatography [hexane-ethyl acetate (7:2)] to obtain ethyl 3-[(4,5-diisopropylfuran-2-carbonyl)amino]benzoate (93 mg, 89%) as colorless needles.

Workup

  1. customthe resultant was purified by silica gel chromatography [hexane-ethyl acetate (7:2)]
