Reaction Steps

1 gm (2.9 mols) of 6-ethoxy-2-methylsulfinyl-5-nitro-4-(1-oxido-thiomorpholino)-pyrimidine [m.p. 164°-165°C, prepared from 6 ethoxy-2-methylthio-5-nitro-4-(1-oxido-thiomorpholino)-pyrimidine and 30% hydrogen peroxide in dilute acetic acid] was refluxed together with 5 gm (58 millimols) of piperazine in 50 ml of ethanol for 10 minutes. The reaction mixture was then poured into water, and the aqueous mixture was extracted with chloroform. The chloroform phase was dried, evaporated to dryness, and the residue was recrystallized from ethanol. Yield: 0.9 gm (84.7% of theory); m.p. 220°-222°C.
