Reaction Steps

3-Bromo-5-methanesulfinylmethyl-pyridine (3.0 g, 13 mmol) is dissolved in chloroform (100 mL) and the solution is cooled to 0° C. Sodium azide (1.3 g, 21 mmol) is added and the reaction mixture is stirred for 5 minutes. Then concentrated H2SO4 (10 mL) is slowly added at 0° C. and then the mixture is heated up to 50° C. for 16 hrs. After cooling down to room temperature, ice cold water is added and the mixture is extracted with CH2Cl2. The aqueous layer is separated, basified with saturated Na2CO3 solution and extracted with more CH2Cl2. Organic layers are combined, dried over anhydrous Na2SO4 and concentrated to give the crude product. Purification by flash column chromatography affords 1.6 g of 3-bromo-5-[imino(methyl)oxo-λ6-sulfanyl]methyl-pyridine.
