Abstract

The invention comprises a sulphur containing derivative of Vitamin B6, believed to have the constitution bis - (4 - hydroxymethyl - 5 - hydroxy - 6 - methylpyridinyl-(3)-methyl)-sulphide, and the preparation thereof by reacting an acid addition salt of 3,4-bis-bromomethyl-5-hydroxy-6-methylpyridine in an aqueous solution with a water soluble inorganic sulphide or hydrogen sulphide. The compound of the invention is characterized by its dihydrochloride and O-tetraacetyl-derivative. The aqueous solution of the 3,4-bis-bromomethyl-5-hydroxy-6-methylpyridine salt is preferably heated several hours before reaction with the sulphide.
