There are two mol­ecules (A and B) in the asymmetric unit of the title compound, C26H32BrN5OS, with almost identical geometry. The morpholine ring adopts the usual chair conformation in both mol­ecules. The triazole ring forms dihedral angles of 4.84 (6) and 74.19 (6)°, respectively, with the bromo­phenyl and isobutylbenzene rings in mol­ecule A, and angles of 16.68 (7) and 87.29 (6)°, respectively, in mol­ecule B. Intra­molecular C—H⋯S hydrogen bonds generate S(5) and S(6) ring motifs in both independent mol­ecules. The crystal structure is stabilized by C—H⋯N, C—H⋯Br and C—H⋯O hydrogen-bonding inter­actions, together with C—H⋯π inter­actions.

Comment top

Mannich reaction is a three-component condensation reaction involving active hydrogen containing compound, formaldehyde and a secondary amine (Raman et al., 2004). The amino alkylation of aromatic substrates by Mannich reaction is of considerable importance for the synthesis and modification of biologically active compounds (Tramontini & Angliolini, 1990). Mannich bases have been reported as potential biological agents. They find applications as antitubercular (Joshi et al., 2004), antimalarial (Lopes et al., 2004), vasorelaxing (Ferlin et al., 2002), anticancer (Holla et al., 2003), and analgesic drugs (Malinka et al., 2005). They are also used in polymer industry as paints and surface active agents (Tramontini et al., 1988). Some Mannich bases are reported to exhibit activity in vitro against murine P388 lymphocytic leukemia cells (Karthikeyan et al., 2006). Similarly, ibuprofen belongs to the class of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) with antipyretic, anti-inflammatory and analgesic properties (Palaska et al., 2002). Previously, we have reported crystal structures of triazole derivatives containing a ibuprofen moiety (Fun, Jebas, Razak et al., 2008; Fun, Jebas, Sujith et al., 2008). In continuation of our work, we report here the crystal structure of the title compound.

The asymmetric unit of the title compound contains two crystallographically independent molecules (A and B) with almost similar geometries. The bond lengths and angles are found to have normal values (Allen et al., 1987). The triazole rings in both molecules are planar with maximum deviations of 0.013 (2) Å and 0.023 (2) Å, respectively, for atoms C8A and N2B. The morpholine ring in both molecules adopt the usual chair conformation with puckering parameters Q = 0.578 (2) Å, θ = 176.6 (2)° and ϕ=152 (3)° in molecule A, and Q = 0.571 (2) Å,θ = 2.0 (2)° and ϕ = 70 (5)° in molecule B (Cremer & Pople, 1975). The N2A/C8A/N3A/N4A/C14A plane forms dihedral angles of 4.84 (6)° and 74.19 (6)°, respectively, with the C1A–C6A and C16A–C21A plane. The dihedral angle formed by the N2B/C8B/N3B/N4B/C14B plane with the C1B–C6B and C16B–C21B planes are 16.68 (7)° and 87.29 (6)°, respectively. Intramolecular C—H···S hydrogen bonds generate S(5) and S(6) ring motifs in both molecules (Bernstein et al., 1995).

The crystal packing is stabilized by intermolecular C—H···N, C—H···Br and C—H···O hydrogen bonding interactions together with C—H···π interactions.

Experimental top

The title Mannich-base compound was obtained by the aminomethylation of its corresponding Schiff base, which was in turn obtained by refluxing a mixture of 4-amino-5-[1-(4-isobutylphenyl)ethyl]-4H-1,2,4-triazole-3-thiol (0.01 mol), 4-bromo-benzaldehyde (0.01 mol) in ethanol (50 ml) and 3 drops of concentrated H2SO4 for 3 h. A mixture of the above Schiff base (0.01 mol), formaldehyde (40%, 1 ml) and morpholine (0.01 mol) in ethanol (50 ml) was stirred at room temperature for 20 h. The solid product obtained was collected by filtration, washed with ethanol and dried. It was then recrystallized using ethanol. Single crystals suitable for X-ray analysis were obtained from acetone-N,N-dimethylformamide (DMF) (1:3) solution by slow evaporation (yield 85%; m.p. 383 K). Analysis for C26H32N5BrOS found (calculated%): C 57.55 (57.564), H 5.81 (5.904), N 12.82 (12.915), S 5.82 (5.904).

Refinement top

H atoms were positioned geometrically (C-H = 0.93-0.98 Å) and refined using a riding model, with Uiso(H) = 1.2-1.5 Ueq(C). A rotating group model was used for the methyl groups.

Experimental. The data was collected with the Oxford Cyrosystem Cobra low-temperature attachment.

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.
