4-Hydroxy-1-methyl-2-oxo-N-(4-oxo-2-propyl-3,4-dihydroquinazolin-3-yl)-1,2-dihydroquinoline-3-carboxamide.
The two bicyclic fragments of the title compound, C(22)H(20)N(4)O(4), are individually planar and are turned with respect to each other by 77.8 (2) degrees. The formation of intramolecular O-H.O and N-H.O hydrogen bonds causes considerable changes in the bond lengths within the amidopyridine fragment.
