The reaction of benzophenothiazin-5-one with aromatic amines proceeds under mineral acid activation of the substrate to generate 6-arylamino derivatives exclusively.N-Alkylanilines give, in addition to the corresponding 6-N-alkyl-N-arylaminobenzophenothiazin-5-ones, the dealkylation product, namely 6-anilinobenzophenothiazin-5-one.
