Abstract: Hydrogen chloride is passed into p-xylene and acetaldehyde to form bis-1-chloroethyl ether; the latter is converted to 2-(1-chloroethyl)-1,4-dimethylbenzene by the action of sulfuric acid and hydrogen chloride. Alkali metal hydrogen sulfide in aqueous methanol or ethanol converts the 2-(1-chloroethyl)-1,4-dimethylbenzene to alpha,2,5-trimethylbenzenemethanethiol; the sodium salt of the latter reacted with 2-chloropyridine-1-oxide yields 2-[1-(2,5-dimethylphenyl)ethylthio]pyridine-1-oxide which is then oxidized with hydrogen peroxide and alkali metal tungstate or tungstic acid to form 2-[1-(2,5-dimethylphenyl)ethylsulfonyl]pyridine-1-oxide.
