Reaction Steps

To a reducing apparatus equipped with a thermometer, reflux condenser and stirrer, 36.5 g (0.0747 mol) of 1,4-bis(3-nitro-5-trifluoromethylphenoxy)benzene, 250 mg of N,N-dimethylformamide and 1.8 g Pd-alumina were charged and reacted in a hydrogen atmosphere at 50° C. for 6 hours. After finishing the reaction, the catalyst was filtered and the filtrate was concentrated under reduced pressure to obtain 1,4bis(3-amino-5-trifluoromethylphenoxy)benzene as colorless crystals. The product was 36.5 g (70.5% yield) and had a melting point of 157.4°~158.0 ° C.
