The synthesis of a series of 2-substituted thiazole-4-carboxamides of 3-aminopropyldimethylsulfonium chloride is described and the proton nmr spectral assignments of these derivatives are made. The compounds, which are fragments and analogs of the DNA-binding portion of the antitumor antibiotic bleomycin A2, will serve as probes of structure-activity relationships in this family of drugs.
