Abstract top

In the molecule of the title compound, C14H20N4O3, the five-membered ring adopts an envelope conformation with the O atom displaced by 0.207 (3) Å from the plane of the other ring atoms. Intramolecular C-H...O hydrogen bonds result in the formation of three five-membered rings having envelope conformations. In the crystal structure, intermolecular N-H...O hydrogen bonds link the molecules, forming R22(20) ring motifs, which produce two-dimensional polymeric sheets extending along the b axis. There are also two C-H...[pi] interactions. The H atoms of one of the methyl groups are disordered over two positions and were refined with occupancies of 0.50.

Comment top

Isobenzofurans exhibit anticonvulsant, antitumour and antiasthamatic properties (Veeraraghavan et al., 1996). These compounds have several biological activities, such as antioxidant, antimycotic, cytotoxic, antimicrobial, herbicidal, analgesic and pesticidal activities (Lin et al., 2005, Roy & Sarkar, 2005, Harper et al., 2003). These are known to exhibit hypotensive and vasorelaxant properties (Tsi & Tan, 1997). We report herein the synthesis and crystal structure of the title compound. This study is in countinuation to the formation of derivatives of O-phthaldehyde with different ureas (Maliha et al., 2007; Maliha, Hussain et al., 2008; Maliha, Tariq et al., 2008).

The molecule of the title compound is essentially symmetric about the mirror plane passing through the O1 atom of the 2-benzofuran ring system as far as the chemical structure is concerned. But, the intramolecular C-H···O hydrogen bonds (Table 1) disturb this symmetry. Due to this reason, there exist R and S-configurations at C1 and C8 atoms, respectively. The bond legths and angles in the 2-benzofuran ring system are in accordance with the corresponding values in 3-[(2-Hydroxy-5-nitrophenyl)amino]-2-benzofuran-1(3H)-one monohydrate (Odabaşoĝlu & Büyükgüngör, 2006). Ring B (C2-C7) is, of course, planar, while the five-membered ring A (O1/C1/C2/C7/C8) adopts envelope conformation with O1 atom displaced by -0.207 (3) Å from the plane of the other ring atoms. The intramolecular C-H···O hydrogen bonds (Table 1) result in the formation of three five-membered rings: C (O3/N3/C1/C13/H1), D (O2/N1/C8/C10/H8) and E (O2/N2/C10/C11/H11A), having envelope conformations with N3, N1 and H11A atoms displaced by 0.191 (3), -0.155 (3) and -0.265 (3) Å from the planes of the other rings atoms, respectively.

In the crystal structure, intermolecular N-H···O hydrogen bonds (Table 1) link the molecules to form R22(20) ring motifs (Bernstein et al., 1995), which are joint in such a fashion that the 2-benzofuran rings are in cis and trans positions. They produce two dimensional polymeric sheets extending along the b axis (Fig 2). There also exist two C–H···π interactions (Table 1).

Experimental top

For the preparation of the title compound, O-phthaldehyde (200 mmol), N,N-dimethylurea (200 mmol) and a few drops of HCl were refluxed in ethanol. Colorless precipitate obtained was crystallized in the solution of methanol:acetone (9:1) by slow evaporation at room temperature.

Refinement top

The hydrogen atoms of the C11 methyl group were disordered over two positions. During the refinement process the disordered atoms were refined with occupancies of 0.50. H1, H8 (for CH) and H2N, H4N (for NH) atoms were located in difference syntheses and refined [C-H = 0.987 (17) and 1.003 (17) Å, Uiso(H) = 1.2Ueq(C); N-H = 0.806 (19) and 0.858 (18) Å, Uiso(H) = 1.5Ueq(N). The remaining H atoms were positioned geometrically, with C-H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for aromatic H atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su'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.
