(57) [PROBLEMS] To provide a novel compound useful as a charge transport material for an electrophotographic photoreceptor or an intermediate thereof, and a method for obtaining the same in a high yield. SOLUTION: N, N'-bis (ethyl ester phenyl)-(1,1'-biphenyl) -4,4'-diamine derivative is obtained from N, N'-diphenylbenzidine by Ullmann reaction and then reduced. In the following chemical formula (I), N, N'-bis (hydroxymethylphenyl)-(1,1 ' -Biphenyl) -4,4'-diamine derivative is obtained. Embedded image |
