1) Application of chloro-acetone or chloro-acetophenone on the Na-salt of p-nitrothiophenol results in p-nitrophenylmercapto-acetone and -acetophenone, respectively. Oxidation of the latter 2 compounds give corresponding sulfone-acetone and -acetophenone. Subsequent bromination of p-nitrophenylmercapto-and sulfone-acetones and -acetophenones and their condensation with thiourea give 2-amino-5-p-nitrophenyl-m rcaptothiazole and -sulfonethiazole.
2) Bromination of p-nitrobenzenesulfone-acetone is discussed.
