Process for the manufacture of 2-mercapto pyridine-1-oxides

A process for the manufacture of 2-mercaptopyridine-1-oxides and zinc salts thereof, comprising the steps of oxidizing a 2-acetylaminopyridine with peracetic acid in an inert solvent to give a 2-acetamidopyridine-1-oxide, cleaving the acetyl group with mineral acid to give a 2-aminopyridine-1-oxide, diazotizing the 2-aminopyridine-1-oxide and treating the diazonium salt with hydrochloric acid to give a 2-chloropyridine-1-oxide, treating the latter with a sulfhydryl-donor to give a 2-mercaptopyridine-1-oxide, and optionally treating the latter with a zinc salt to make the 2:1 zinc salt of the 2-mercaptopyridine-1-oxide. The resulting zinc salts are useful in anti-dandruff preparations.
