실험 절차
1.9 gm (0.005 mol) of 8-methylthio-4-(1-oxido-thiomorpholino)-2-piperazino-pyrimido-[5,4-d]-pyrimidine (m.p.: 253°-255° C.) were heated with 25 ml of benzylamine for about one hour at 150° C. Subsequently, the excess amine was largely distilled off in vacuo, the residue was taken up in about 150 ml of water, and the solution was adjusted to pH 7 with dilute hydrochloric acid. The precipitated reaction product was suction-filtered off, washed with water and dried.
