An equimolar mixture of 4-(4-methylbenzoyl)-5-(4-methylphenyl)furan-2,3-dione (0.50 g), easily obtained from oxalyl dichloride and 4,4'-dimethyldibenzoylmethan, as described by Ziegler et al. (1967), and 4-methylacetophenone semicarbazone (0.34 g) (molar ratio 1:1) were refluxed in 30 ml boiling toluene for 4 h. After evaporation of the solvent, the oily residue was treated with dry diethyl ether to give a yellow precipitate, which was filtered off and recrystallized from ethanol (yield: 0.35 g, 50%; m.p. 488 K). IR (KBr, ν, cm-1): 3050, 3044, 2920 (aromatic and aliphatic C—H), 1690, 1645 (s, C═O), 1602–1473 (m, C═C and C═N aromatic rings); 1H NMR (200 MHz, DMSO, p.p.m.): δ 8.47 (s, 1H at C-6), 7.94–7.13 (m, 12H, Ar—H), 2.39, 2.33, 2.31, 2.27 (s, 12H, 4xCH3). Analysis Calculated for C28H25N3O2: C 77.21, H 5.78, N 9.64%; found: C 77.40, H 5.57, N 9.50%.
H atoms were positioned geometrically and treated using a riding model, fixing the bond lengths at 0.96 and 0.93 Å for CH3 and CH(aromatic), respectively. The displacement parameters of the H atoms were constrained as Uiso(H)= 1.2Ueq(1.5Ueq for methyl groups). Riding methyl H atoms were allowed to rotate freely during refinement using the AFIX 137 command of SHELXL97 (Sheldrick, 1997).

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. |

4-Aroyl-5-aryl-2,3-dihydro-2,3-furandiones represent easily accessible building blocks for the synthesis of heterocyclic systems (Altural et al., 1989; Kollenz et al., 1991; Sarıpınar et al., 2000; Hökelek et al., 2002; Yıldırım et al., 2002). In general, pyrimidines have been found much interest for their widespread potential biological activities (Kleemann & Engel, 1982) and medicinal applications, thus their chemistry has been investigated extensively (Brown, 1984, 1985). Some of them are frequently encountered in many drugs used for the treatment of hypothyroidism, hypertension, cancer chemotherapy or HIV infection (Burdge, 2000). Furthermore many condensed heterocyclic systems, especially when linked to a pyrimidine ring, play an important role as analgesic, antipyretic and anti-inflammatory drugs (Vega et al., 1990), and also as herbicides (Chakaravorty et al., 1992), and plant growth regulators (Shishoo & Jain, 1992). In view of these important properties, we have undertaken the X-ray diffraction study of the title compound, (I).
The structure of the title compound, (I), is shown in Fig. 1. The structure of (I) contains one central pyrimidine ring (N1/N3/C2/C4—C6) with a p-tolylethylideneamino group (N11/C11—C19) substituted at N1, an O atom substituted at C2, a p-tolyl group (C41—C47) substituted at C4 and a methylbenzoyl group substituted at C5. The plane of the pyrimidine ring makes dihedral angles of 35.86 (6), 41.57 (4) and 52.18 (4)° with the (C13—C18), (C41—C46) and (C52—C57) phenyl rings, respectively·The pyrimidine ring is not planar with a maximum deviation of -0.1032 (9) Å for atom C2. The interatomic distances and angles show no anomalies.
In the molecular structure, there is a π—π stacking interaction between the (C41—C46) and (C52—C57) phenyl rings with a distance of 3.749 Å between the ring centroids, and a perpendicular distance between the rings of 3.483 Å. In the crystal structure of (I), atom C53 in the molecule at (x, y, z) acts as hydrogen-bond donor to the O2 atom in the molecule at (1 - x, 1 - y, 2 - z), so generating by inversion a dimeric unit characterized by an R22(18) motif (Bernstein et al., 1995). The dimers are connected to one another via another C—H···O interactions in which atom C19 in the molecule at (x, y, z) acts as hydrogen-bond donor to the O2 atom in the molecule at (x, y - 1, z), forming one dimensional dimeric chain along the [010] direction.
