S-n-Butylthiuronium bromide is prepared by reacting together n-butyl bromide, thiourea and ethyl alcohol. S-Cetylthiuronium iodide, S-amidoethylthiuronium chloride (using chloracetamide), S-2-thiazylamidomethylthiuronium chloride, and S-2-pyridylamidomethylthiuronium chloride are similarly prepared. 2-Chloracetamidothiazole is prepared by reacting 2-aminothiazole with chloracetyl chloride in pyridine, and precipitating with acetic acid. 2-Chloracetamidopyridine is similarly prepared.
