To pure N-phenyl-0-phenylenediamine(17 mmol,3.128 g) in ethanol(10 ml), 4-methoxy benzaldehyde(17 mmol,2.1 ml) and ammonium acetate(3 g) was added for about 1 h while maintaining the temperature at 80°C. The reaction mixture was refluxed and the completion of reaction was monitored by TLC, finally the reactants extracted with dichloromethane. The solid separated was purified by
using petroleum ether as the eluent.Yield:2.65 g(50%) from which it was crystallized.All the hydrogen atoms were geometrically fixed and allowed to ride on their parent atoms with C—H = 0.93 - 0.97 Å, and Uiso(H) = 1.2Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All e.s.d.'s are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

The benzimidazole core is classified by medicinal chemists as one of the 'privileged substructures' for drug design,in light of the affinity they display towards a variety of enzymes and protein receptors (Mason et al.,1999).
The synthesis of benzimidazoles has received much attention owing to the varied biological activity such as antifungal (Pawar et al., 2004), antiviral (Tomei et al., 2003), antiHIV (Rao et al., 2003), antidiabetic (Minoura et al., 2004), antimicrobial and anticancer (Demirayak et al., 2002), properties exhibited by a number of derivatives of these compounds.
Benzimidazole derivatives possess antioxidant activities (Jayabharathi et al.,2012).
They have emerged as potent non nucleoside inhibitors of HIV-1 reverse transcriptase (Roth et al.,1997, Morningstar et al.,2007)
It also acts as a specific inhibitors of the NS5B polymerase of the hepatitis C virus (HCV) (Beaulieu, et al., 2004).
The molecular structure of (I), is shown in Fig.1. The (N1/N2/C8—C14) 1H-benzimidazole ring is planar. It forms dihedral angles of 48.00 (6)° and 64.48 (6)° with the mean planes of the C2—C7 and C15—C20 phenyl rings respectively.
The C1—O1—C2—C7 and C3—C2—O1—C1 torsion angles are 2.8 (2)° and -176.42 (14)° respectively.
A C6—H6···π interaction involving the phenyl ring of methoxybenzene at the symmetry code [1 - x,1/2 + y,1/2 - z] and C13—H13···π interaction involving the benzene ring of benzimidazole at the symmetry code [2 - x,1/2 + y,1/2 - z] are also found.
