Reaction Steps

200 mg (1.05 mM) of 5-chloro-1-ethyl-3-mercaptopyrazin-2(1H)-one, 178 mg (1 mM) of 2-chloro-N-phenylacetamide and 135.6 mg (1.05 mM) of diisopropylethylamine in 5 ml of tetrahydrofurane were stirred overnight at room temperature. Water was added and the precipitate was filtered and washed with water, to give 170 mg of 2-[(6-chloro-4-ethyl-3-oxo-3,4-dihydropyrazin-2-yl)thio]-N-phenylacetamide. Yield: 50%.
