Participants

Reaction Steps

148.4 g (0.25 mol) of the 2,2-bis (4-nitrobenzoyloxyphenyl) propane obtained in Reference Example 5 was dispersed in 500 ml of ethanol charged into a 1-liter four-neck flask equipped with a reflux condenser, thermometer, agitator and dropping funnel, and 2.5 g of 10% palladium supported activated charcoal was added, 66 g (1.05 mol) of hydrazine was added over a period of 30 minutes using the dropping funnel, with caution to rapid refluxing, and the refluxing was continued for 3 hours. After the reaction, the precipitate was removed and the filtrate was concentrated by an evaporator and recrystallized with ethanol. 111.5 g (yield: 86.7%) of 2,2-bis(4-aminobenzoyloxyphenyl)propane was obtained.
