Procedure: Into a 100 ml glass reactor equipped with a reflux condenser and a stirrer, 20 g (0.091 mol) of the tetrafluorophthalic anhydride prepared in Example 3 and 32.2 g (0.091 mol) of tri-n-octylamine were charged and 3.5 g (0.109 mol) of methanol was dropwise added thereto. Then, the mixture was reacted at 140° C. for 4 hours. After completion of the reaction, the reaction mixture was separated by distillation to obtain 17.5 g of 3,4,5,6-tetrafluorobenzoic acid methyl ester. The yield was 92.3%. Into a 100 ml glass reactor equipped with a reflux condenser and a stirrer Then, the mixture was reacted at 140° C. for 4 hours After completion of the reaction the reaction mixture was separated by distillation
