Abstract
2-Chloro-1-methylpyridinium iodide reacts rapidly and quantitatively with thiol groups in the presence of excess of triethylamine to give the 2-alkyl(aryl)thio-1-methylpyridinium iodide and an equimolar amount of hydrogen chloride which is trapped by the triethylamine. The excess of triethylamine is back-titrated with hydrochloric acid, with Bromothymol Blue as indicator.
