Abstract

1-Thiocarbamoylthiosemicarbazide, the synthetic equivalent of thiourea and thiosemicarbazide, reacts with phenylchloropyruvic acid methyl ester exclusively as thiourea (Hantzsch reaction) forming 2-hydrazo-4-methoxycarbonyl-5-phenylthiazole. Diacetylation and reductive fission of this hydrazo compound was carried out, and also oxidation to the corresponding azo compound, readily accomplished with using dimethyl sulfoxide.
