The central eight-membered ring of the title compound, C40H36N8O2, deviates from the ideal boat conformation because the bond between the exo-ethylene group and the adjacent N atom is twisted by 60.0 (4)° due to Its adjacent benzene and pyrazole rings are oriented almost perpendicular to each other, making a dihedral angle of 85.8 (3)°. In the crystal, the molecules are linked by C(ar)—H⋯O hydrogen bonds, generating a three-dimensional network.

A mixture of 2-acetamido-N-methyl-N-(3-methyl-1-phenyl-1H-pyrazol-5-yl)benzamide (14.5 mmoles) and phosphorus oxychloride (50 ml) was refluxed for 1 h. Excess phosphorus oxychloride was evaporated under reduced pressure and the reaction mixture was poured into crushed ice mixed with solid sodium bicarbonate and extracted with chloroform (3x150 ml): the organic layers were washed with water, dried (sodium sulfate) and concentrated under reduced pressure to dryness to give a residue, which was crystallized from ethanol affording the title compound (yield 1.75 g).
All non-H-atoms were refined anisotropically. Hydrogen atoms were located by difference Fourier synthesis, except methyl and phenyl hydrogen atoms, that were introduced at calculated positions, in their described geometries and allowed to ride on the attached carbon atom with fixed isotropic thermal parameters 1.2Ueq and 1.5Ueq of the parent carbon atom for aromatic H-atoms and methyls H-atoms, respectively. For the methyls bound to the sp2-carbons, a rotating-group model was used. The crystal contains solvent accessible voids, however, no electron density peaks were found in chemically sensible positions for solvent molecules.

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. |

We performed the Bischler-Napierlaski reaction (Plescia et al., 1979) on 2-acetamido-N-methyl-N-(3-methyl-1-phenyl-1H-pyrazol-5-yl)benzamide by phosphorus oxychloride under reflux, obtaining an unexpected product related to a benzodiazocine system, whose corrected structure is now reported (Fig. 1). Single-crystal X-ray analysis on the reaction product allows to assign the formation of the title compound. The molecule crystallizes in a non-centrosymmetric space group: the possibility of the centrosymmetric space group C2/c was discounted by lack of a suitable solution and by the wholly satisfactory refinement in the space group Cc. The overall conformation of the molecular structure is determined by the central macrocycle formed by three fused cycles: a pyrazole, an eight-membered ring in the middle and a benzene. The central ring deviates from the ideal boat conformation because the bond between the exo-ethylene group and the adjacent nitrogen atom is twisted by 60 (1)° due to steric hindrances. The C12—C17 benzene and the pyrazole belonging to the tricyclic moiety are rather perpendicularly oriented (dihedral angle of 86 (1)°). The chain linked to N4 is characterized by a curled conformation, as defined by the torsion angles C20—N5—C22—C23 of -125 (1)° C22—C23—C28—N6 of -75 (1)° and C23—C28—N6—C30 of -10 (1)°. The benzene C22—C27 forms with the phenyl of the macrocycle a dihedral angle of 75 (1)°, while it makes a dihedral angle of 59 (1)° with the distal pyrazole unit. The latter moiety bears the C34—C39 ring quite rotated, as shown by the torsion angle N7—N8—C34—C35 of -41 (1)°. The phenyl C1—C6 linked to the fused pyrazole is rotated by 136 (1)°, as indicated by the torsion angle N2—N1—C1—C6. The molecular packing is stabilized by rather weak intermolecular Cπ—H···O type hydrogen bonds between C36—H36···O1i of 2.55 (1) Å and 153 (3)° [symmetry code: (i) x + 1/2, 3/2 - y, z - 1/2], and C15—H15ii···O2 at distance of 2.57 (1) Å, angle 124 (1)° [symmetry code: (ii) x, 2 - y, z + 1/2] (Fig. 2).
