The asymmetric unit of the title compound, C19H16FN5O4, contains two independent mol­ecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4)°. Weak π–π stacking inter­actions may be effective in the stabilization of the crystal structure.

Comment top

Pyridopyrimidines are annelated uracils that have attracted considerable interest in recent years. Their derivatives have been known to display a wide range of pharmacological activities, such as antitumor (Sanghhvi et al., 1989), antiviral (Tenser et al., 2001) and antifungal (Nizamuddin-Mishra et al., 2001). Therefore, for the preparation of these complex molecules large efforts have been directed towards the synthetic manipulation of uracils. As a result, a number of reports have appeared in the literature that usually describe forcing conditions, long reaction times and complex synthetic pathways. Thus, new routes for the synthesis of these molecules have attracted considerable attention allowing for a rapid entry to these heterocycles. Microwave-assisted organic synthesis is an increasingly popular field as indicated by numerous publications in the past few years owing to several advantages, such as enhanced reaction rates and increase in yields under milder conditions (Perreux & Loupy, 2001). In light of the above, we have synthesized the title compound, (I), under microwave-assisted conditions and characterized its structure.

In the molecule of (I), (Fig. 1), the bond lengths and angles are generally within normal ranges (Allen et al., 1987) and may be compared with the corresponding ones in similar structures (Bazgir et al., 2006a,b). The asymmetric unit contains two independent molecules.

Rings A (N1/N2/C87C9/C11), B (N3/C7/C8/C13/C14/C19), C (N4/N5/C14/C16/C187C19) D (C1—C6) and A' (N6/N7/C27/C28/C30/C32), B' (N8/C26/C27/C32/C33/C38), C' (N9/N10/C33/C35/C37/C38), D' (C20—C25) are, of course, planar and the dihedral angles between them are A/B = 2.62 (2), A/C = 5.08 (3), B/C = 2.48 (2) and A'/B' = 7.58 (2), A'/C' = 12.28 (3), B'/C' = 4.92 (3)°.

The weak π-π stacking interactions, involving the adjacent rings with centroid-centroid distance of 3.507 (4) %A [symmetry code: x, y + 1/2, z] may be effective in the stabilization of the crystal structure.

Experimental top

6-Amino-1,3-dimethyluracil (310 mg, 2 mmol), 4-fluorobenzaldehyde (124 mg, 1 mmol) and montmorillonite K10 (400 mg) were mixed together. The reaction mixture was placed in a screw-capped vial and irradiated for 5 min with microwave irradiation (700 W). After cooling, the reaction mixture was washed with ethanol and then recrystallized from ethyl acetate to afford the pure product (yield; 210 mg, 53%, m.p. 543–545 K).

Refinement top

H atoms were positioned geometrically with C—H = 0.93 and 0.96 Å, for aromatic and methyl H atoms, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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.
