SYNTHESIS AND ANTIMICROBIAL SCREENING OF CERTAIN SUBSTITUTED CHALCONES AND ISOXAZOLINES BEARING HYDROXY BENZOFURAN
ABSTRACT 3-Hydroxy Bezofura
4-Amino-2,8-dimethyl-6H-pyrimido[1,2-a][1,3,5]triazin-6-one1
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 the carbonyl group. In the crystal, molecules are linked via intermolecular N—H⋯N hydrogen bonds into chains of C
