In the title compound, C₂₆H₂₈FN₅O₃, the morpholine ring adopts a chair conformation. The piperazine ring is puckered [Q_T = 0.5437 (15) Å, θ = 8.89 (15) and φ = 357.2 (11)°]. The 1,6-dihydropyridazine ring makes dihedral angles of 28.03 (7) and 77.46 (7)° with the phenyl and benzene rings, respectively. In the crystal, molecules are linked along the c axis by C—H⋯O interactions and are flattened parallel to the ac plane. C–H⋯π interactions also contribute to the stability of the structure.

Comment top

In recent years, the 3(2H)-pyridazinone system has aroused a great deal of attention due to its structural relationship to pyrazolone derivatives such as aminopyrine and dipyrone in view of the ring enlargement of pyrazolone to pyridazinone. These drugs possess analgesic and anti-inflammatory activities although they have limitations for their clinical use due to serious side effects such as blood dyscrasias (Şüküroğlu et al., 2006; Brogden, 1986).

A series of 6-morpholino-4-aryl-3(2H)-pyridazinone alkanoic acids, their ester and amide derivatives were prepared and tested for their in vivo analgesic activity by using the p-benzoquinone-induced writhing test. The title compound, C₂₆H₂₈FN₅O₃, generally showed higher activity but caused gastric ulceration in the animals (Şüküroğlu et al., 2006).

In the title molecule (I), Fig. 1, the morpholine ring (N3/O2/C11–C14) adopts a chair conformation. The piperazine ring (N4/N5/C17–C20) is puckered. The conformation of this ring is described by three puckering parameters: Q_T = 0.5437 (15) Å, θ = 8.89 (15) ° and, ϕ = 357.2 (11) ° (Cremer & Pople, 1975). The 1,6-dihydropyridazine ring (N1/N2/C7–C10) makes dihedral angles of 28.03 (7) and 77.46 (7) ° with the C1–C6 phenyl and C21–C26 benzene rings, respectively. The phenyl and benzene rings make a dihedral angle of 50.17 (8) ° with each other. In the crystal structure, molecules are linked along the c-axis direction and are flattened parallel to the plane containing the a and c axes. Furthermore, C–H···π interactions contribute to the stability of the structure (Table 1). Fig. 2 shows the packing diagram of (I) down the b axis.

Theoretical calculations were carried out using the semiempirical quantum-mechanical CNDO/2 (Complete Neglect of Differential Overlap) method (Pople and Beveridge, 1970). The spatial view of the single molecule calculated as closed-shell in a vacuum is shown in Fig. 3 with atomic labels. The calculated dipole moment of (I) is about 2.795 Debye. The HOMO and LUMO energy levels are -10.013 and 0.832 eV, respectively.

According to the theoretical CNDO/2 and experimental X-ray structural results, the values of the geometric parameters of (I) are almost comparable within the experimental error interval (Allen et al., 1987).

The 1,6-dihydropyridazine ring (N1/N2/C7–C10) forms dihedral angles of 2.24 and 60.48° with the C1–C6 phenyl and C21–C26 benzene rings, respectively. The dihedral angle between the phenyl and benzene rings is 62.62°. The orientations of the planes of the rings are however, slightly different in the CNDO/2 and X-ray results. That is, intermolecular interactions play an important role in determining the crystal state conformation of (I).

Experimental top

A reaction mixture containing 2-[4-phenyl-6-(morpholin-4-yl)-3(2H)- pyridazinone-2-yl]acetic acid (0.01 mole) and triethylamine (0.011 mole) in 20 ml dichloromethane at 273 K (ice-bath) was treated with ethyl chloroformate (0,01 mole). After stirring the reaction mixture at 273 K for 15 min, 0.011 mole of 4-(4-fluorophenyl)-piperazine derivative was added to this solution. The final mixture was stirred at room temperature for 24 h and evaporated to dryness and then acetone was added. All undissolved salts were filtered off, the filtrate was evaporated to dryness and the residue was recrystallized from acetone-water (1:1) to yield 62%, [m.p.: 457 K].

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement on F² for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The observed criterion of F² > σ(F²) is used only for calculating -R-factor-obs 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.
