W. Dai and D.-W. Fu

Abstract: In the title compound, C₁₅H₁₉N₃O₃, owing to an intramolecular O-HN hydrogen bond, the pyridine and imidazole rings are nearly coplanar and are twisted from each other by a dihedral angle of only 0.92 (9)°. The molecules are linked through intermolecular N-HO hydrogen bonding, forming an infinite chain parallel to the b axis.
