ABSTRACT:
The invention provides a novel compound 2-(3-trimethylsilylpropyl)benzothiazole having remarkable anti-tumor effects or, in particular, inhibiting growth of melanoma cells in test animals. The compound is synthesized by the ring-closing intramolecular dehydration condensation of 2-mercapto-(.gamma.-trimethylsilyl)butyroanilide which in turn is obtained by the dehydrochlorination condensation of 2-aminothiophenol and .gamma.-trimethylsilylbutyryl chloride in a polar solvent in the presence of an acid acceptor.
