3-[4-(3,5,6-trimethyl-1,4-benzoquinon-2-ylmethyl)phenyl]propionic acid (25 mg, 0.08 mmol), isopropylamine (0.010 ml, 0.12 mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (28 mg, 0.12 mmol) in dry methylene chloride (1 ml) were stirred at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure and was purified by a silica gel column chromatography (methylene chloride:ethyl acetate=4:1) to obtain the title compound (18 mg, 0.051 mmol, yield 64%).
