Source of material
A mixture of 7-methoxy-2-naphthol (0.01 mol), malononitrile (0.01 mol), benzaldehyde (0.01 mol), ethanol (30 mL) and piperidine (0.5 mL) was heated under reflux for 1 h. After complete precipitation occurred the solid product was collected by filtration, washed by methanol and recrystallized from ethanol to give the title compound as colourless crystals; yield 89%; M.p.: 528–529 K.
Experimental details
Carbon-bound hydrogen atoms were placed in calculated positions and were included in the refinement in the riding model approximation. The H atoms of the methyl groups were allowed to rotate with a fixed angle around the C—C bond to best fit the experimental electron density.
Discussion
Chromene and benzochromene derivatives have attracted considerable interest owing to their biological and pharmaceutical activities such as antibacterial [1, 2, 3], antifungal [4, 5, 6], vascular-disrupting [7], antioxidant [8, 9], anticancer [10, 11, 12, 13], estrogenic anticoagulant and antispasmolytic [14], antileishmanial [15], antiproliferative and apoptosis inducing [16, 17, 18, 19].
In the title structure the asymmetric unit contains one independent molecule. All bond lengths and angles are in the expected ranges. The phenyl ring (C16—C20) is perpendicular to the plane of the rest of the molecule (84°). The molecules are connected in the crystal structure via two symmetry related strong classical intermolecular hydrogen bonds, N1—H2N1⋯N2i (H⋯A distance = 2.20(3) Å; N—H⋯N angle = 162(3)°; symmetry code: (i) −x + 1, −y + 1, −z + 2).
