Abstract

In the title compound, C₂₉H₂₃ClN₂O, the 5-chloro­phenol ring and the imidazole ring are nearly coplanar, with a dihedral angle of 15.76 (9)° between them. The ethyl­phenyl ring and the two phenyl rings subtend angles of 71.09 (7), 43.95 (5) and 36.53 (9)°, respectively, with the imidazole plane. An intra­molecular O—H⋯N hydrogen bond supports the mol­ecular conformation, and an inter­molecular C—H⋯O inter­action, originating from an ortho-phenyl H atom, stabilizes the packing arrangement. In addition, a weak C—H⋯π inter­action, also involving an ortho-phenyl H atom, is observed.

Structure description

The imidazole moiety is known to play an important role in biological systems being a part of the histidyl residue in peptides and proteins (Sigel et al., 2000 ▸). Multi-substituted imidazoles are an important class of heterocyclic compounds that exhibit diverse biological activities such as anti-inflammatory (Gaonkar et al., 2009 ▸), anti­leishmanial (Bhandari et al., 2010 ▸) and anti­cancer (Ozkay et al., 2010 ▸) activities. As part of our ongoing studies in this area, we herein report the synthesis and crystal structure of the title compound, 4-chloro-2-(1-(4-ethyl­phen­yl)-4,5-diphenyl-1H-imidazol-2-yl)phenol (Fig. 1 ▸). The 5-chloro­phenol ring, two phenyl rings and the ethyl­phenyl ring are substituents on the central five-membered imidazole ring (C1/N2/C3/C2/N1). The imidazole and the 5-chloro­phenol rings are close to coplanar with a dihedral angle of 15.76 (9)° between them. The imidazole ring subtends at dihedral angles of 71.09 (7), 43.95 (5) and 36.53 (9)° with the ethyl­phenyl ring and the two phenyl rings (C18–C23 and C24–C29), respectively. A strong intra­molecular O1—H1⋯N1 hydrogen bond is formed between the O1 atom of the 5-chloro­phenol group and atom N1 of the imidazole ring (Fig. 2 ▸), forming an (6) graph-set motif, which stabilizes the close to coplanar arrangement of the imidazole and phenol rings.

In the crystal, atom C19 of the phenyl ring and the hydroxyl O1 atom of the phenol group are involved in a weak C19—H19⋯O1ⁱ inter­action that links the mol­ecules along the a-axis direction (Fig. 2 ▸). Thus the hydroxyl O atom acts as both a hydrogen-bond donor and an acceptor. The crystal structure is further consolidated by a C15—H15⋯Cg ⁱⁱ inter­action with the aryl ring (Table 1 ▸, Fig. 2 ▸).

Synthesis and crystallization

The title compound was synthesized by the one-pot reaction of benzil (10 mmol), 4-ethyl­aniline (10 mmol) and 5-chloro-2-hy­droxy­benzaldehyde (10 mmol) with ammonium acetate (10 mmol) in a glacial acetic acid (20 ml) medium. The mixture was refluxed for 5 h at 343 K, the progress of the reaction being monitored by TLC. After completion of the reaction, the mixture was cooled to room temperature and poured into 100 ml of ice-cold water. The resulting precipitate was filtered, dried and further purified by column chromatography (7:3 petroleum ether:ethyl acetate) and isolated in good yield (85%). The product was recrystallized from ethanol solution.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. H atoms were placed at calculated positions in the riding-model approximation, with O—H = 1.00 Å and C—H = 0.93, 0.96 and 0.97 Å for aromatic, methyl and methine H atoms, respectively, and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) otherwise.
