A new class of pyridodipyrimidines, 8-alkoxypyrido [2, 3-d : 6, 5-d']-dipyrimidine-2, 4, 6 (3H, 10H, 7H)-triones (2) were synthesized by the reaction of 6-alkylamino-3-methyluracils (1) with appropriate trialkyl orhtoformates in dimethylformamide and their structures were unambiguously established by the X-ray diffraction analysis of 2f.
