4-Amino-2,8-dimethyl-6H-pyrimido[1,2-a][1,3,5]triazin-6-onePart 15 in the series `Fused heterocyclic systems with s-triazine ring'. For Part 14, see Dolzhenko et al. (2009a).
In the title compound, C8H9N5O, the mean planes through the pyrimidine and triazine rings form a dihedral angle of 2.83 (16)°. The amino group adopts a trigonal-planar configuration and forms an intramolecular resonance-assisted N—H...O=C hydrogen bond with t...
