A method is known for obtaining pyrimido[5,4-th]-pyrimidines of the general formula by reducing the compound of general formula-1 B10, where two of the radicals Ri, R2, Rs and R4 are a free or substituted amino group or a free or substituted hydrazino or guanidino group, and the other two are hydrogen or halogen, an alkyl or aryl radical, an hydroxy group free or substituted by an alkyl, Ery;!-yl'I diethylamioethyl group, a mercapto group, free or substituted by an alkyl or an aryl radical. npa and one more of the Zi, Z^, Zg and Z4 radicals is hydrogen or halogen, alkyl or aryl, an hydroxy group free or substituted by an alkyl, aryl or diethylaminoethyl group, a mercapto group free or substituted by an alkyl or aryl radical, or a free or substituted amino group. We propose a method.
