Reaction Steps

500 mg (2.30 mM) of 3-mercapto-1-propylpyrazin-2(1H)-one, 319.2 μl (1.21 mM) of 4-chlorobenzylbromide and 637 mg (4.6 mM) of potassium carbonate in 4 ml of tetrahydrofurane were stirred overnight at room temperature. Water was added and the aqueous layer was extracted with ethyle acetate. The organic layer was separated and washed with water, dried on anhydrous sodium sulfate and evaporated under vacuum, to give an oil which was purified by silica gel column chromatography, using dichloromethane/dimethylketone (98/2) as eluant, to give 600 mg of 3-[(4-chlorobenzyl)thio]-1-propylpyrazin-2(1H)-one. Yield: 88%.
