Reaction Steps

To a reducing apparatus equipped with a thermometer, reflux condenser and stirrer, 33 g (0.0585 mol) of 4,4'-bis(3-nitro-5-trifluoromethylphenoxy) biphenyl, 100 ml of methyl cellosolve and 1.7 g of 5%-Pd/c having a moisture content of 50% were charged and reacted in a hydrogen atmosphere at 70°~80° C. for 4 hours. After finishing the reaction, the catalyst was filtered off. The filtrate was concentrated under reduced pressure to obtain 4,4'-bis(3-amino-5-trifluoromethylphenoxy) biphenyl as light yellow crystals.
