| Popis: | The title compound, C20H19N3O3·C3H7NO, was synthesized by the reaction of 6-aminopyrimidine-2,4(1H,3H)-dione and 4-methylbenzaldehyde with 5,5-dimethyl-1,3-cyclohexanedione in 1-butyl-3-methylimidazolium bromide at 363 K. The pyrimidine ring adopts a half-chair conformation while the six-membered ring fused to the pyridine ring adopts a skew-boat conformation. The dihedral angle between the pyridine ring and the attached benzene ring is 2.38(8)° |
