(Received 21 July 2010; accepted 24 July 2010; online 31 July 2010)

In the title compound, C22H17N3O5, synthesized via the aza-Wittig reaction of ethyl 3-(phenyl­imino­methyl­ene­amino)­benzofuran-2-carboxyl­ate, benzene isocyanate and diethyl 2-amino­succinate, the imidazo[1,2-a]benzo[4,5]furo[2,3-d]pyrim­idine ring system is essentially planar (r.m.s. deviation for all 16 non-H atoms = 0.020 Å). The phenyl ring is twisted with respect to this ring system, making a dihedral angle of 54.23 (4)°. The crystal packing is stabilized by weak inter­molecular C—H⋯O inter­actions.

Comment top

The derivatives of benzofuropyrimidine are of great importance because of their remarkable biological properties. Some of them have shown good analgesic, anti-inflammatory and antimicrobial activities (Moneam et al., 2004 and Bodke et al., 2003). On the other hand, heterocycles containing an imidazolone nucleus also exhibit various biological activities. Several of them have shown good antibacterial, antifungal activities or are used as leukotriene B4 receptor antagonist and potassium channel openers (Palacios et al., 2007 and Duval et al., 2005, Teimouria et al., 2006). The introduction of an imidazolone ring to the benzofuro[3,2-d]pyrimidin-4(3H)-one system is expected to influence the biological activities significantly. As a part of our ongoing investigations on the preparation of derivatives of heterocyclic compounds (Hu et al., 2005, 2006, 2007, 2008), we have synthesized and structurally characterized the title compound, and here we report its crystal structure (Fig. 1).

In the crystal structure of the title compound, all ring atoms of imidazo[1,2-a]benzo[4,5]furo [2,3-d]pyrimidine system are essentially coplanar, with maximum deviations -0.039 (3)Å and 0.057 (1)Å for O3 and N2, respectively. The phenyl (C11—C16) ring is twisted with respect to it, making dihedral angles of 54.23 (4)°. The structure is mainly stabilized by weak C—H···O interactions.

Experimental top

The title compound was obtained in excellent yield via aza-Wittig reaction. Crystals suitable for single-crystal X-ray diffraction were obtained by recrystallization from a mixed solvent of ethanol and dichloromethane (1:2 v/v) at room temperature.

Refinement top

All H-atoms were found in a difference map but positioned with idealized geometry and refined with Uiso(H)= 1.5Ueq(C) for methyl H atoms and Uiso(H) =1.2Ueq(C) for all other H atoms using a riding model with C—H ranging from 0.93Å to 0.97Å.

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.
