A newsynthesis of push-pull pyrroles of type 5 was developed starting from bis(imidoylchlorides) 1 and various iminodiacetic acid derivatives 3. The use of appropriate N-trifluoroacetyl residues as protecting/activating group proved to be the method of choice for the straightforward preparation of the 3,4-diarylamino-1H-pyrroles 5. When benzothiazole substructures are present in 2,5-position of heterocycles
