Abstract: The asymmetric unit of the title compound, C19H19N3O4, contains two molecules with very few conformational differences; a C atom in the pyrimidine ring in one of the molecules is disordered in a 0.688 (15):0.312 (15) ratio. In both molecules, the fused pyridine and pyrimidine rings adopt half-chair conformations. The dihedral angles between the furan and benzene rings are 81.00 (13) and 84.99 (10)° in the two molecules. The molecular structure is consolidated by intramolecular N-HO hydrogen bonding. In the crystal, C-HO hydrogen bonds connect the molecules into a three-dimensional network.
