Reaction Steps
German Published Application DAS 1,191,652 states that, for example, pyridinium ethylsulfate (2-pyridinium-1-sulfatoethane) can be prepared in an expensive procedure by reacting hydroxyethylpyridinium chloride, obtained from pyridine and ethylenechlorohydrin, with chlorosulfonic acid. In this procedure too, the yield and purity are unsatisfactory.
