2-MERCAPTOPYRIDINE N-OXIDE Usage And Synthesis

Chemical Properties

OFF-WHITE TO YELLOWISH GRANULAR CRYST. POWDER

Preparation

A solution of 60 gm (0.284) of 2-bromopyridine N-oxide hydrochloride is neutralized with 25% aqueous sodium hydroxide. In a well-ventilated hood, to this solution, heated with stirring on a steam bath, is added dropwise over a 1-hr period a solution of 32 gm (0.57 mole) of sodium hydrogen sulfide in 150 ml of water. After the addition has been com­pleted, heating is continued for 0.5 hr. The reaction mixture is cooled, filtered, and acidified with 6 Ν hydrochloric acid to afford 24 gm (67%), m.p. 65-68°C. Upon recrystallization from aqueous ethanol, the melting point is raised to 68-70°C.
Similar results were obtained when an equivalent quantity of sodium sulfide was substituted for sodium hydrogen sulfide.
