Reaction Steps

Next, in a 300 mL recovery flask, the obtained 81.3 g of 2,2′-dihydroxy-3,3′-dinitro-5,5′-bis[3-(1-adamantyl)-(1-adamantyl)]-biphenyl (0.10 mol), 0.318 g of 10% palladium-activated carbon (0.30 mmol), 273 mL of N,N-dimethylformamide and a stirrer were charged and agitated at 25° C. for 24 hours under a hydrogen atmosphere. A reaction solution was filtered and then added to 1 L of ion-exchange water. Solid precipitate was collected by filtration, then agitated in 1 L of ion-exchange water for one hour and dried under reduced pressure, thus obtaining 69.3 g of 2,2′-dihydroxy-3,3′-diamino-5,5′-bis[3-(1-adamantyl)-(1-adamantyl)]-biphenyl (0.092 mol; the yield was 92.0%).
