8,8-Dimethyl-5-(4-methylphenyl)-8,9-dihydropyrimido[4,5-b]quinoline-2,4,6(1H,3H,7H)-trione N,N-dimethylformamide solvate

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...

description 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)°
