2.0 g (11.0 mM) of 2,3,5,6-tetrafluorohydroquinone, 0.87 g (5.5 mM) of nonanoic acid, 1.13 g (5.5 mM) of dicyclohexylcarbodiimide and a catalytic amount of 4-pyrrolidinopyridine were added to 20 ml of tetrahydrofuran, followed by stirring for 3 hours at room temperature. After the reaction, the insoluble residue was filtered off, followed by distilling-off of the solvent to obtain a crude product. The crude product was purified by silica gel column chromatography (eluent: toluene) to obtain 0.57 g of an objective product (Yield: 32.2%).
