(Received 7 January 2012; accepted 12 January 2012; online 21 January 2012)

In the title compound, C24H25N3O5, the benzimidazole and benzodioxole ring systems are each approximately planar [maximum deviations = 0.043 (1) and 0.036 (1) Å, respectively]. Their mean planes form a dihedral angle of 42.85 (4)°. The pyrrolidine ring has an envelope conformation with one of the methyl­ene C atoms forming the flap. In the crystal, weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network. The crystal packing is further stabillized by weak π–π inter­actions between the benzene rings within the benzimidazole ring system [centroid–centroid distance = 3.7955 (7) Å]. A weak C—H⋯π inter­action involving the benzodioxole ring is also present.

Comment top

2-substituted benzimidazoles are proven important drug leads. They have therefore generated pharmacological interests (Grassmann et al., 2002; Demirayak et al., 2002; Evans et al., 1997). As part of our ongoing structural studies of benzimidazole derivatives (Yoon et al., 2012a,b,c), we now report the structure of the title compound (I).

In (I), the benzimidazole, (N1–N2/C1–C7) and benzodioxole, (O4–O5/C8–C13/C24) rings are approximately planar with a maximum deviation of 0.043 (1) Å at atom N1 and 0.036 (1) Å at atom O4, respectively. The mean plane through the benzimidazole ring makes a dihedral angle of 42.85 (4) ° with the mean plane through the benzodioxole ring. The pyrrolidine ring adopts an envelope conformation with puckering parameters, Q = 0.2094 (17) Å and ϕ = 64.7 (4)° and atom C21 at the flap (Cremer & Pople, 1975).

In the crystal (Fig. 2), intermolecular C5—H5A···O5(x,-y+1/2,z-1/2), C15—H15B···O3(2-x,1-y,2-z), C21—H21A···O31(-x,-1/2+y,3/2-z) and C24—H24B···O3(1-x,-y,2-z) interactions link the molecules into a three-dimensional network. In addition, π–π interactions are observed which involve the benzimidazole ring system between the benzene, (C1–C6;centroid Cg1) rings with a Cg1···Cg1(2-x,1-y,2-z) distance of 3.7955 (7) Å. The crystal packing is further stabilized by weak C—H···π interactions (Table 1) involving the benzodioxole rings.

Experimental top

Ethyl 3-amino-4-(3(2-oxopyrrolidin-1yl)propylamino)benzoate (0.84 mmol) and sodium metabisulfite adduct of piperonal (1.68 mmol) were dissolved in DMF. The reaction mixture was reflux at 403K for 2 hrs. After completion, the reaction mixture was diluted in ethyl acetate (20 mL) and washed with water (20 mL). The organic layer was collected, dried over Na2SO4 and the evaporated in vacuo to yield the product. The product was recrystallised from ethyl acetate.

Refinement top

All the H atoms were positioned geometrically and refined using a riding-model approximation with with C–H = 0.95–0.99 Å. The Uiso values were constrained to be 1.5Ueq (methyl-H atom) and 1.2Ueq (other H atoms). The rotating model group was applied for the methyl group.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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. 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 > 2sigma(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.
