Reaction Steps

12 gm (0.037 mol) of 6-ethoxy-2-chloro-5-nitro-4-(1-oxido-thiomorpholino)-pyrimidine were stirred together with 22 gm (0.28 mol) of piperazine in ethanol at 40°C for 2 hours. Then, the reaction mixture was poured into water, and the precipitate formed thereby was suction-filtered off and recrystallized from ethanol. Yield: 13 gm (93.8% of theory); m.p. 223°-224°C.
