ABSTRACT

The title compound, C19H15NO3, was synthesized by a Perkin reaction of 2-methyl-8-hy­droxy­quinoline and 4-formyl-2-methyl­benzoate in acetic anhydride under a nitro­gen atmosphere. The mol­ecule has an E conformation about the C=C bond, and the quinoline ring system and the benzene ring are inclined to one another by 29.22 (7)°. There is an intra­molecular O—H⋯N hydrogen bond in the 8-hy­droxy­quinoline moiety. In the crystal, mol­ecules are linked by pairs of O—H⋯O hydrogen bonds, forming inversion dimers with an R22(28) ring motif. The dimers are linked by C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming sheets parallel to plane (10-1).
