Abstract
Disclosed is a process for forming a N,N′-diarylquinacridone compound comprising the step of reacting a 1,4-dialkylcarboxylate-2,5-bis(N -arylamino) benzene with an iodoaryl compound to form the corresponding 2,5 -bis(N-diarylamino) compound. The process is versatile and provides high yields and purity for the synthesis of N,N′-diarylquinacridone compounds.
