실험 절차

A solution of 3, 4 gm (0.01 mol) of 8-ethylthio-2-chloro-4-(1-oxido-thiomorpholino)-pyrimido-[5,4-d]-pyrimidine (m.p. 197°-199° C.) in 100 ml of dimethylsulfoxide was slowly poured, while stirring, into a solution of 4.3 gm (0.05 mol) of piperazine in 75 ml of dimethylsulfoxide at 40° C., and the mixture was stirred for 1 hour at 40° C. The reaction mixture was then taken up in about 1 liter of water, whereby the reaction product slowly precipitated in crystalline form. After standing for a short period of time, the precipitate was suction-filtered off, washed with water and dried at about 70° C.
