Into a reducing device equipped with a thermometer, a reflux condenser and an agitator were charged 55 g of 1,3-bis(3-nitrophenoxy)-5-trifluoromethylbenzene (0.131 mol), 150 g of methyl cellosolve and 5 g of 5%-Pd/C (50% of water content), and the mixture was reacted at 70 to 80° C. for 4 hours in an atmosphere of hydrogen. At the end of the reaction, the catalyst was filtered out and the filtrate was heated to 90° C., to which 140 g of water was added. The mixture was cooled to room temperature to crystallize the desired product, which was filtered and dried under a reduced pressure to give 1,3-bis(3-aminophenoxy)-5-trifluoromethylbenzene as a white solid; Melting point: 98.0 to 98.6° C., Yield: 41 g (87%).
