paper describes the preparation of 4′-amino (2) and 4′-nitro (3) derivatives of 4-N,N-dimethylaminotriphenylmethane as precursors for presumed DNA-binding metabolites of malachite green. The primaryamine2 was synthesized via a condensation of 4-lithiated bis-(N,N-trimethylsilyl)aniline and 4-(dimethylamino)benzophenone. A simple nitro-dediazoniation reaction of 2 failed to afford 3, but gave exclusively
