3,4-Dihydro-2,6,7-trimethyl-4-oxo-3-(2-pyridyl)quinazoline-8-carboxylic Acid

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—H...O hydrogen bonds determine the crystal packing.
