Abstract

PURPOSE: Pyrimido [ 4.5 - d ] pyrimidine derivatives of formula I ( where R1 is phenyl or substituted phenyl; R2 is lower alkyl, substituted lower alkyl, unsaturated alkyl or alcoxycarbonyl). For example, 1 - (m - trifluoromethylphenyl) -3 - ethoxycarbonylmethylpyrimido [ 4,5 - d ] pyrimidine - 2, 4 ( 1 H,3 H) - dione.
