New 4-amino-pyrimido-pyrimidine derivs
4-Amino-pyrimido(5,4-d)pyrimidine derivs. of formula (I) are new: Ra = H or alkyl; Rb = phenyl substd. by R1-R3; R1, R2 = H, halo, 1-6C alkyl, etc.;Q1-Q3, where Q1 = 4- to 7-membered alkyleneimino, Q2 = 5- to 7-membered alkyleneimino with 1-2 N-adjacent CH2 gps. replaced by CO and Q3 = 6- or 7-membe...
