Reaction Steps

Successively, to a reduction vessel equipped with a thermometer, reflux condenser and stirrer, 120 g (0.195 mol) of 1,3-bis[4-(4-nitro-6-methylphenoxy)-α, α-dimethylbenzyl]benzene, 400 g of isopropyl alcohol and 5 g of 5%-Pd/c having a moisture content of 50% were charged and reacted at 70°~80° C. for 4 hours in a hydrogen atmosphere. After finishing the reaction, the catalyst was filtered off and the filtrate was concentrated under reduced pressure to obtain 89.0 g (82% yield) of 1,3-bis[4-(4-amino-6-methylphenoxy)-α, α-dimethylbenzyl]benzene as a light yellow crystal having a melting point of 118.1~118.2.
