Reaction Steps

In a 5 L recovery flask, 48.4 g of 3,3′-dibromo-5,5′,7,7′-tetramethyl-1,1′-biadamantane (100 mmol), 688 g of phenol (7.3 mol) and a stirrer were charged and agitated at 155° C. for 30 minutes under nitrogen flow. After cooling the mixture to room temperature, 4.3 L of ion-exchange water was added thereto and agitated at 80° C. for ten minutes. Solid precipitate was collected by filtration, then washed with 7 L of ion-exchange water and dried under reduced pressure, thus obtaining 50.6 g of 3,3′-bis(4-hydroxyphenyl)-5,5′,7,7′-tetramethyl-1,1′-biadamantane (99.0 mmol; yield: 99.0%).
