Some Aspects of the Chemistry of Pyridopyrimidines. A Novel s-Triazolopyridopyrimidine

The novel 7-hydrazino-1,3-dimethylpyridopyrimidine-2,4(1H,3H)-dione (2) gives the hydrazine derivatives 3, 5, 6, 8, and 10.The s-triazolopyridopyrimidine 4 is prepared from 3, while the attempted cyclizations of 5, 6, and 8 failed.Two pyridopyrimidines substituted in position 6 are prepared, 13a from 11 and benzoylacetonitrile, 16 by photo-Fries rearrangement of 15.In CDCl3 solution and in solid phase predominates the tautomeric OH form 16I.
