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...

Summary: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-membered alkyleneimino with a CH2 gp. in the 4 posn. replaced by O, S, SO, SO2 or NQ (Q = H, alkyl, alkanoyl, alkylsulphonyl, aryl or aralkyl) and Q1-Q3 are opt. substd. by 1-4 alkyl gps.; COQ1, SO2Q1, COQ3 or SO2Q3; opt. N-alkyl-substd. alkanoylamino, alkylsulphonylamino, aroylamino, arylsulphonylamino, aralkanoylamino, aralkylsulphonylamino or perfluoroalkylsulphonyl, etc.;R3 = e.g. H; or adjacent R2+R3 = e.g. a methylenedioxy;Rc = H, halo, alkyl, 3-7C cycloalkyl, etc.;all alkyl fragments are 1-4C unless stated otherwise.
