Synthesis and Structure of as-Triazinoquinazolines, II.

4-Amino-3-(methylthio)-6-R-1,2,4-triazin-5(4H)-ones 6-10 react with anthranilic acid to yield the 1-amino-3-R-2H-as-triazinoquinazoline-2,6(1H)-diones 17-21 rather than the expected as-triazinobenzotriazepines 12-16.Compounds 17-21 were deaminated into compounds 22-26.Heating of the N-benzylidene derivatives of 6-10 (27-31) with anthranilic acid also led to the formation of 22-26 with extrusion of benzonitrile.
