Zusammenfassung:1526235 Pyrimidine derivatives ASTRA PHARMACEUTICALS AB 20 Oct 1975 [21 Oct 1974] 42995/75 Heading C2C Compounds of Formula I may be prepared by reacting 2,4-diamino-6- hydroxypyrimidine with 3,4,5 - trimethoxybenzaldehyde in a solvent to form an intermediate reaction product of probable formula followed by reduction of the above intermediate product. When the first reaction step is carried out in the presence of water, the intermediate is obtained in the form of a complex of formula
