In the title compound, C18H15N3O2, the benzo­furan ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, mol­ecules are linked by weak N—H⋯N, N—H⋯O and C—H⋯O inter­actions, generating edge-fused R44(20), and R12(7) rings linked into sheets which are parallel to (010).

The title compound (±)-3-(5-amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)isobenzofuran-1(3H)-one, (I), is part of the study of different crystal systems, associated with isobenzofuranones, which are an important class of synthetic and natural occurring products exhibiting diverse biological and pharmacological properties. Particularly, several of its 3-substitued derivatives are part of the framework of natural products such as fuscinarin with anti-HIV properties (Yoganathan et al., 2003), typhaphthalide, a phenolic compound isolated from Typha capensis (Shode et al., 2002), noscapine, with antitussive and anticancer properties (Anderson et al., 2005), rubiginone-H, as antibiotic (Puder et al., 2000), spirolaxine with antibacterial activity against Helicobacter pylori (Nannei et al., 2006), cytosporone E with antibacterial properties (Brady et al., 2000) and some synthetic spirolactones as inhibitors of the influenza virus type B (Malpani et al., 2013). Continuing with our current studies on the use of pyrazoles for the synthesis of diverse pyrazole-derivatives with synthetic and biological interest (Abonia et al., 2010; Insuasty et al., 2012; Insuasty et al., 2013), compound (I) was obtained from the reaction of 2-formylbenzoic acid with 5-amino-3-methyl-1-phenylpyrazole. In order to present the molecular conformation of (I) and its supramolecular behavior, the title compound was synthesized. The molecular structure of (I) is shown in Fig. 1. In the present molecule rings A (C2—C7) and B (O1—C1—C2—C7—C8) are planar showing a dihedral angle between them A/B = 0.57 (9)°. The phenyl, A and B rings form dihedral angles of 47.07 (10)°, 85.76 (7)° and 86.04 (7)° with the pyrazole ring respectively.

Further analysis showed that each molecule is linked to other molecules by weak N—H···N, N—H···O and C—H···O interactions (see table 1, Nardelli, 1995). These intermolecular contacts are explained in terms of the substructure shown in figure 2. The N3 atom in the molecule at (x,y,z) acts as hydrogen bond donor to pyrazolic N1 atom at (x,-y - 1/2,+z + 1/2). At the same time the N3 atom is linked to another molecule via N—H···O. Indeed, the N3 atom in the molecule at (x,y,z) acts as hydrogen bond donor to C=O O2 atom in the molecule at (x +1,-y - 1/2,+z + 1/2). Growth of the crystal is reinforced by the weak interaction C11—H11···N1, in which the C11 atom of the benzofuranone ring at (x,y,z) acts as hydrogen-bond donor to atom N1 in the molecule at (x,-y - 1/2,+z + 1/2). The combination of these intermolecular contacts generate edge-fused R44(20), and R21(7) (Fig. 2) ring motifs (Etter, 1990; Bernstein et al., 1995), as sheets which stack parallel to (010).

Experimental top

Reagents and solvents for the synthesis were obtained from the Aldrich Chemical Co., and were used without additional purification. The 5-amino-3-methyl-1-phenyl-1H-pyrazole (117 mg, 0.68 mmol) and 2-formylbenzoic acid (103 mg, 0.69 mmol) were dissolved in a mixture of MeCN/H2O (10:1, 2 mL). The solution was stirred at room temperature for 24 h until the starting materials were not detected by TLC. Then, the solid formed was filtered and washed with cold MeCN (1 mL) without further purification (See scheme 2). White crystals of (I) suitable for single-crystal X-ray diffraction were grown by slow evaporation, at ambient temperature and in air, from a solution in ethanol (87% yield, m.p. 464 (1) K). MS (ESI+): m/z found: 306 [M+H]+, 328 [M+Na]+; elemental analysis found: C 71.13, H 5.01, N 13.69%; C18H15N3O2 requires: C 70.81, H 4.95, N 13.76%.

Refinement top

All H-atoms were positioned at geometrically idealized positions [N—H= 0.86 Å, C—H= 0.93 Å for aromatic, C—H= 0.96 Å for methyl group] and refined using a riding model approximation with Uiso(H) constrained to 1.2 (N—H and aromatic) and to 1.5 (methyl) times Ueq of the respective parent atom. Coordinates for H11 were freely refined.

Special details top

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.
