organic compounds
The title compound, C17H15N3O3, has a very short intramolecular O—H
N hydrogen bond, which closes a six-membered ring and forces an almost coplanar disposition of the carboxyl group with respect to the quinazoline ring plane. The dihedral angle between the least-squares planes of the quinazoline system and the pyridine ring is 86.8 (1)°. The C—HO hydrogen bonds determine the crystal packing.
