4.68 gm (0.03 mol) of 2-mercapto-5-nitro-pyridine were dissolved, while gently heating, in a sodium hydroxide solution prepared by dissolving 1.32 gm (0.033 mol) of sodium hydroxide in 60 ml of water. 4.17 gm (0.033 mol) of dimethylsulfate were added to this solution, and the mixture was shaken well. The resulting precipitate was filtered off with suction, and the still moist product was recrystallized from ethanol. 2-Methylthio-5-nitro-pyridine was obtained.
