Abstract top

In the title compound, C25H26N4O3, the two fused pyrrolo[3,2-d]pyrimidine rings form a dihedral angle of 3.7 (2)°. The two substituent phenyl rings are twisted with respect to the pyrrole and pyrimidine rings, making dihedral angles of 57.2 (2) and 69.0 (2)°, respectively. The ethyl and ethoxy groups are disordered over two positions; the site occupancies are 0.53 (1) and 0.47 (1) for ethyl, and 0.63 (1) and 0.37 (1) for ethoxy. The crystal packing features C-H...O hydrogen bonds.

Comment top

As a part of our ongoing work in the preparation of derivatives of heterocyclic compounds (Hu et al., 2006, 2007, 2010; He et al., 2007a,b; Ma et al. 2009; Zeng et al., 2008), we have synthesized and structurally characterized the title compound (Fig. 1). In the molecule, the two fused rings of pyrrolo[3,2-d]pyrimidine form a dihedral angle of 3.7 (2)°. The attached two phenyl rings are twisted with respect to the heterocyclic pyrrolo[3,2-d]pyrimidine system, making dihedral angles of 56.8 (2)° and 69.3 (2)°, respectively. The ethyl group (C13—C14) is disordered over two sites with occupancies that refined to 0.53 (1) and 0.47 (1); the ethoxy group (C18—C19) is also disordered over two sites with occupancies 0.63 (1) and 0.37 (1). The crystal packing is stabilized by intermolecular C—H···O hydrogen bonds. There are no π-π interactions.

Experimental top

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

Special details top

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.
