(Received 27 November 2012; accepted 29 November 2012; online 5 December 2012)

The title compound, C27H28N2O, is a lophine (2,4,5-triphenyl-1H-imidazole) derivative with an n-pentyl chain on the amine N atom and a 4-meth­oxy substituent on the benzene ring. The two phenyl and meth­oxy­benzene rings are inclined to the imidazole ring at angles of 25.32 (7), 76.79 (5) and 35.42 (7)°, respectively, while the meth­oxy substituent lies close to the plane of its benzene ring, with a maximum deviation of 0.126 (3) Å for the meth­oxy C atom. In the crystal, inversion dimers linked by pairs of C—H⋯O hydrogen bonds generate R22(22) loops. These dimers are stacked along the a-axis direction.

Comment top

The chemilumescence properties of lophine, (2,4,5-triphenyl-1H-imidazole), and its derivatives have been known since the late 19t h century (Radziszewski, 1877) and their non-linear optical (Santos et al., 2001) and related optical properties (Maeda & Hayashi, 1969, 1970) have been extensively investigated. In addition, substituted imidazoles exhibit a wide range of biological activities for example as glucagon receptors (Laszlo et al., 1999), CB1 cannabinoid receptor antagonists (Eyers et al., 1998) and modulators of P-glycoprotein (P-gp)-mediated multi drug resistance (MDR) (Newman et al., 2000). They can also act as both antibacterial (Antolini et al., 1999) and antitumor agents (Wang et al., 2002) or as pesticides (Veisi et al., 2012). As part of our work on the synthesis of imidazole derivatives, we have prepared 2-(4-methoxyphenyl)-1-pentyl-4,5-diphenyl-1H-imidazole and report its preparation and structure here.

In the title compound, the lophine (2,4,5-triphenyl-1H-imidazole) skeleton (Yanover & Kaftory, 2009a) is embellished with a nicely ordered C22—C26 n-pentyl substituent on the amine N atom of the imidazole ring and a p-methoxy substituent on the C17—C21 benzene ring. The n-pentyl chain is almost orthogonal to the imidazole with a meanplane through C22···C26 (r.m.s. deviation = 0.047 /%A) that subtends a dihedral angle of 78.91 (7) ° to the plane of the imidazole ring. The two C4···C9 and C10···C15 phenyl rings are inclined to the imidazole ring at angles of 25.32 (7)°, 76.79 (5)° respectively while the methoxy substituted C17···C21 ring makes and angle of 35.42 (7)°. The methoxy substituent lies close to the plane of the C17···C21 benzene ring with a maximum deviation of only 0.126 (3) Å for the C119 atom. Bond distances in the structure are normal (Allen et al., 1987) and are comparable to those reported for related structures (Yanover & Kaftory, 2009a,b; Kison & Opatz, 2009; Zhao et al., 2012). In the crystal structure the only significant intermolecular contacts are C15—H15···O119 hydrogen bonds which form inversion dimers with R22(22) ring motifs (Bernstein et al., 1995). These dimers are further stacked along the a axis (Fig. 2), with alternating molecules arranged in a head to tail fashion (Fig. 3).

Experimental top

A 50-ml. volumetric flask equipped with a magnetic stirring bar was charged with 25 ml. of dimethyl sulfoxide and 2.4 g (40 mmol) potassium hydroxide. The mixture was stirred at room temperature for 5 minutes, then 3.26 g (10 mmol) 2-(4-methoxyphenyl)-4,5-diphenyl-1H-imidazole was added with stirring for a further 45 minutes. To this reaction mixture, 3.02 g. (20 mmol) pentyl bromide was added. After stirring for an additional 45 minutes the mixture was diluted with 20 ml water then extracted with diethyl ether (3x 20 ml). The combined ether layers were dried over calcium chloride and evaporated under slightly reduced pressure. The excess pentyl bromide was removed by distillation at approximately 15 mm, and the residue was crystallized from ethanol yielding 3.35 g (84%) of 2-(4-methoxyphenyl)-1-pentyl-4,5-diphenyl-1H-imidazole, m.p. 382–384 K.

Refinement top

All H-atoms bound were refined using a riding model with d(C—H) = 0.95 Å, Uiso=1.2Ueq (C) for aromatic, 0.99 Å Uiso=1.2Ueq (C) for methylene and 0.98 Å, Uiso = 1.5Ueq (C) for CH3 H atoms.

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
