Procedure

To 250 mg (1.23 mM) of 3-bromo-1-ethylpyrazin-2(1H)-one and 340.3 mg (2.46 mM) of potassium carbonate in 4 ml of THF were added 159 μl (1.35 mM) of benzylthiol. The reaction mixture was then stirred at room temperature for 16 h. Water was added and the organic phase was extracted with ethyle acetate. The combined organic layer was washed with water, dried on anhydrous sodium sulfate and the solvent was removed under vacuum, to give a solid, which was triturated in diisopropyle oxide, filtrated and dried under vacuum, to give 250 mg of 3-(benzylthio)-1-ethylpyrazin-2(1H)-one. Yield: 82%.
