In the first step, 2-methylthiobenzothiazole (Aldrich Chemical Company, Milwaukee, Wis. is quaternized by heating at 120° C. with an equivalent of methyl p-toluenesulfonate (Compound 1A, also commercially available from TCI, Portland, Oreg.). N-(3-iodopropyl)-4-methylquinolinium iodide (Compound 1B) is prepared by heating lepidine (5.0 g, 35 mmol) with 100 g (340 mmol) of diiodopropane at about 100° C. for one hour. Ethyl acetate is added and filtered. Compounds 1A and 1B are condensed to yield
