실험 절차

α,α′-Diphenyl-α-hydroxyl-p-xylene was prepared as shown in Scheme 4 by using 29.0 g (117 mmol) of 4-bromo diphenylmethane and 11.2 g (106 mmol) of benzaldehyde/19.7 g (106 mmol) by the similar procedure to the method for preparing 4-bromobenzhydrol. The crude product was dissolved in chloroform and filtered through G60 column filled with silica gel. After evaporating the solvent, the result product was recrystallized with hexane/chloroform (9:1 v/v) to provide a yield of 86%. MP: 64° C.
