In the title compound, C23H27N3O5, the pyrazole ring is inclined at dihedral angles of 38.16 (6) and 80.80 (6)°, respectively, to the least-squares planes of the benzene and dihydropyridine rings. In the crystal, adjacent molecules are linked via a pair of N—H⋯N hydrogen bonds, forming an inversion dimer. The dimers are stacked in a column along the a axis through N—H⋯O hydrogen bonds. Intra- and intermolecular C—H⋯N and C—H⋯O hydrogen bonds are also observed.

3-(4-Methoxyphenyl)-1H-pyrazole-4-carbaldehyde (0.2g, 0.80 mmol), ethylacetoacetate (0.26g, 1.6 mmol) and ammonium acetate (0.07g, 0.90 mmol) in ethanol (20 ml) were refluxed for 8 hours in an oil bath. After the completion of the reaction, the reaction mixture was concentrated and poured into crushed ice. The precipitated product was filtered and washed with water. The resulting solid was recrystallized from hot ethanol (yield: 0.32g, 76%; m.p. 453–455 K).
Atom H1N1 and H1N2 were located from a difference Fourier maps and refined freely [N—H = 0.880 (17)–0.906 (17) Å]. The remaining H atoms were positioned geometrically (C—H = 0.95–0.98 Å) and were refined using a riding model, with Uiso(H) = 1.2 or 1.5Ueq(C). A rotating group model was applied to the methyl groups.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

Substituted pyridines are important structural components of a variety of biologically active compounds. They possess anti-inflammatory, anti-microbial (Surendra Kumar et al., 2011), anti-oxidant, anti-tumor and anti-ulcer activities (Swarnalatha et al., 2011). In view of these activities, herein we report the crystal structure of the title compound.
The molecular structure of the title compound is shown in Fig. 1. The pyrazole (N2/N3/C14–C16) ring is approximately planar with maximum deviation of 0.003 (1) Å for atom N2. The central pyrazole (N2/N3/C14–C16) ring makes dihedral angles of 80.80 (6) and 38.16 (6)° with the pyridine (N1/C1–C5) ring and the benzene (C17–C22) ring, respectively. The dihedral angle between the pyridine (N1/C1–C5) ring and the benzene (C17–C22) ring is 44.88 (5)°.
In the crystal packing, (Fig. 2), the adjacent molecules are connected via intra- and intermolecular N2—H1N2···O1, N1—H1N1···N3, C6—H6B···N3, C7—H7A···O3, C14—H14A···N1, C18—H18A···O1 and C22—H22A···O3 hydrogen bonds.
