Procedure
8.1 gm (0.02 mol) of 8-(N-benzyl-methylamino)-2-chloro-4-(1-oxido-thiomorpholino)-pyrimido[5,4-d]pyrimidine (melting point: 158°-160° C.) were heated at about 90° C. for one hour with 12.2 gm (0.2 mol) of 2-hydroxyethyl-amine. The mixture thus obtained was taken up in about 250 ml of water, whereby the reaction product separated out as a precipitate which soon solidified. It was filtered off, washed with water and dried at about 60° C. Yield: 8.2 gm (96% of theory).
