    Description / Table of Contents: Synthese und Struktur von as-Triazinochinazolinen, II1)Die 4-Amino-3-(methylthio)-6-R-1,2,4-triazin-5(4H)-one 6 - 10 ergaben bei der Umsetzung mit Anthranilsäure die 1-Amino-3-R-2H-as-triazino[3,2-b]chinazolin-2,6(1H)-dione 17 - 21 anstelle der erwarteten as-Triazino[3,4-b][1,3,4]benzotriazepine 12 - 16. Die Verbindungen 17 - 21 ließen sich zu 22 - 26 desaminieren. Erhitzen der N-Benzylidenderivate von 6 - 10 (27 - 31) mit Anthranilsäure führte unter Freisetzung von Benzonitril ebenfalls zu 22 - 26.
    Notes: 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-triazino[3,2-b]quinazoline-2,6(1H)-diones 17 - 21 rather than the expected as-triazino[3,4-b][1,3,4]benzotriazepines 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.
