Reaction Steps

To a reaction apparatus equipped with a thermometer, reflux condenser and stirrer, 60 g (0.131 mol) of 3,3'-dinitro-4,4'-diphenoxybenzophenone, 150 g of methyl cellosolve and 3.0 g of 5%-Pd/C (50% moisture content) were charged and reacted in a hydrogen atmosphere at 70°~80° C. for 4 hours. After finishing the reaction, the catalyst was filtered and the filtrate was concentrated under reduced pressure to obtain 45 g (86% yield) of 3,3'-diamino-4,4'-diphenoxybenzophenone as light yellow crystals.
