1-(4-Methoxy­phen­yl)imidazolidine-2,4-dione

Abstract

In the title compound, C₁₀H₁₀N₂O₃, the dihedral angle between the benzene and imidazolidine rings is 6.0 (4)°, consistent with an essentially planar mol­ecule. In the crystal, inter­molecular N—H⋯O hydrogen bonding between centrosymmetrically related mol­ecules leads to loosely associated dimeric aggregates. These are connected into a three-dimensional network by C—H⋯O inter­actions, as well as π–π inter­actions [centroid–centroid distances = 3.705 (3) and 3.622 (3) Å] between the imidazolidine and benzene rings.

Comment

During an investigation of new anti-diabetic drugs, we found that imidazolidinediones (IZD's) have good anti-diabetic activities. The crystal structure determination of the title compound, (I), was undertaken to investigate the relationship between structure and anti-diabetic activity.

In title compound, C₁₀H₁₀N₂O₃, bond lengths and angles are normal and in a good agreement with those reported previously (Gerdil, 1960). The dihedral angle between the benzene ring (C4—C9) and imidazolidine ring (C1—C3/N1/N2) is 6.0 (4) °. In the crystal packing, intermolecular N—H···O hydrogen bonding between centrosymmetrically related molecules lead to loosely associated dimeric aggregates, Table 1. These aggregates are connected into the 3-D crystal structure by C—H···O and π–π interactions, the latter occurring between the imidazolidine and benzene rings, Table 1.

Experimental

Compound (I) (1.13 g, 55% yield) was prepared according to the reported procedure of (Niwata et al., 1997), using 1-(4-methoxyphenyl)urea (0.010 mol; Kurzer et al., 1963), sodium hydride (0.022 mol), N,N-dimethylformamide (20 ml), and ethyl chloroacetate (0.0120 mol. Colourless single crystals suitable for X-ray diffraction analysis were obtained by recrystallization from a mixture of methanol and water (1:1 V/V).

Refinement

All C-bound H atoms were found on difference maps, but included in the final cycles of refinement using a riding model with C—H = 0.95–0.99 Å, and with U_iso(H) = 1.2U_eq(C) for aryl- and methylene-H atoms, and 1.5U_eq(C) for the methyl H atoms. The N–H1 atom was refined freely.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
