実験手順
10.4 gm (0.035 mol) of 2-chloro-8-methylthio-4-morpholino-pyrimido-[5,4-d]-pyrimidine (m.p. 179°-180° C.) were heated with 28.5 gm (0.25 mol) of N-formyl-piperazine at about 100° C. for 30 minutes. The resulting solution was taken up in about 300 ml of water, whereby the reaction product was obtained as yellowish precipitate. The precipitate was suction-filtered off, washed with water and dried at 70° C.
