Abstract
The title compound, C29H42N4O5·0.5H2O, comprises four structural units. A flexible propyloxy unit in a gauche conformation, with a –C(H2)—C(H2)—C(H2)—O– torsion angle of −64.32 (18)°, connects an isoxazole ring and an approximately planar phenyloxadiazole ring system [with a maxixmum devation of 0.061 (2) Å], which are oriented almost parallel to one another with a dihedral angle of 10.75 (7)°. Furthermore, a C11-alkyl chain with a terminal hydroxy group links to the 3-position of the isoxazole ring via an amide bond. In the crystal, a half-occupancy solvent water molecule connects to a neighbouring molecule via an intermolecular O—H⋯O(water) hydrogen bond to the C11-alkyl chain hydroxy group.
Chemical context
An antiviral drug family of the so-called ‘WIN compounds’ was developed against various human illnesses caused by enteroviruses including common respiratory infections, rash or mild fever and serious or life-threatening infections, such as meningitis, myocarditis, encephalitis and paralytic poliomyelitis (De Palma et al., 2008 ▸; Diana, 2003 ▸). The WIN compounds were particularly designed to target the early events (attachment, entry and uncoating) of viral replication and they have been shown to bind specifically into the interior hydrophobic pocket located at the VP1 protein of the enterovirus capsid and replacing the naturally occurring myristic acid (Reisdorph et al., 2003 ▸; Giranda et al., 1995 ▸; Zhang et al., 2004 ▸; Thibaut et al., 2012 ▸). The antiviral drug candidate development finally led to the WIN 63843 analogue, better known as Pleconaril, which showed a drastic decrease in the metabolic degradation of the molecule and a broad range of antiviral activity against enteroviruses (Pevear et al., 1999 ▸; Wildenbeest et al., 2012 ▸). The design of the title compound is based on the chemical structure of the WIN 61893 analogue (Diana et al., 1995 ▸), to which an additional C11-alkyl linker arm having a hydroxy end group was attached at the 3-position of the isoxazole ring via an amide bond.
Structural commentary
The molecular structure of the title compound is shown in Fig. 1 ▸. The structure contains three essentially planar heterocyclic or aromatic rings, i.e. isoxazole (atoms C19–C21/N22/O23), benzene (C7–C12) and oxadiazole (C2/O3/N4/C5/N6), of which the latter two are directly connected via atoms C7 and C5. The three heterocyclic rings are approximately coplanar to one another, having dihedral angles between the rings of 11.57 (8) (C19–C21/N22/O23 and C7–C12), 10.68 (9) (C19–C21/N22/O23 and C2/O3/N4/C5/N6) and 4.81 (9)° (C7–C12 and C2/O3/N4/C5/N6), maintaining the WIN framework in a linear conformation. The dihedral angle between the isoxazole ring (C19–C21/N22/O23) and the approximately planar phenyloxadiazole ring system [C7–C12/C2/O3/N4/C5/N6, with a maximum devation of 0.061 (2)Å for atom C12] is 10.75 (7)°. The isoxazole and phenyloxadiazole ring systems are connected by a propyloxy unit (O15–C18), which is in a gauche conformation, with a C18—C17—C16—O15 torsion angle of −64.32 (18)°. The amide group (N26–C24) at the 3-position of the isoxazole ring which joins the C11-alkyl chain (C27–O38) and the WIN framework is likewise almost coplanar with the isoxazole ring, with a dihedral angle of 10.92 (9)° between the amide (H26/N26/C24/O25) and isoxazole planes. The amide hydrogen (H26) and the acidic isoxazole hydrogen (H20) are on opposite sides, with a torsion angle (N26—C24—C21—C20) of 172.31 (15)°. The C11-alkyl chain (C27–C37) is in an all-anti conformation, with an average torsion angle of 178.80°. The WIN framework and the C11-linker arm structural units are aligned roughly in a 160° angle and the total length of the title molecule measures up to 3.4 nm.

Supramolecular features
The title compound packs in the crystal lattice in layers, in which the molecules are held together by solvent-mediated O—H⋯O and C—H⋯O hydrogen bonds (motif 1), as well as C—H⋯N and C—H⋯O intermolecular interactions between the heterocyclic isoxazole and phenyloxadiazole units of neighbouring molecules (motif 2) (Table 1 ▸). In the solvent-mediated assembly, an intermolecular hydrogen-bonded network of the type
(9) is formed between the C11-alkyl chain hydroxy [O—H⋯O = 1.90 (1) Å], solvent water [O—H⋯O = 1.87 (1) Å], amide carbonyl and isoxazole hydrogen (C—H⋯O = 2.56 Å) groups of two parallel neighbouring molecules (Fig. 2 ▸). In a similar manner, two pairs of C—H⋯N and C—H⋯O hydrogen bonds connect three opposite-facing neighbouring molecules via R
2
2(8) and
(16) loops between the isoxazole (C—H⋯O = 2.51 Å) and phenyloxadiazole (C—H⋯O = 2.64 Å and C—H⋯N = 2.65 Å) groups (Fig. 2 ▸).

Database survey
A search of the Cambridge Structural Database (CSD; Version 5.36, November 2014; Groom & Allen, 2014 ▸) revealed the presence of nine structures (CSD refcode VOGDAY contains two independent molecules; Salorinne et al., 2014 ▸) with the substructure 3-{3,5-dimethyl-4-[3-(3-methylisoxazol-5-yl)propoxy]phenyl}-5-methyl-1,2,4-oxadiazole. These nine structures belong to three similar compounds of 5-{3-[2,6-dimethyl-4-(5-methyl-1,2,4-oxadiazol-3-yl)phenoxy]propyl}isoxazole-3-carboxylic acid (Salorinne et al., 2014 ▸), ethyl 5-{3-[2,6-dimethyl-4-(5-methyl-1,2,4-oxadiazol-3-yl)phenoxy]propyl}isoxazole-3-carboxylate (Salorinne et al., 2014 ▸) and 3-{3,5-dimethyl-4-[3-(3-methylisoxazol-5-yl)propoxy]phenyl}-5-trifluoromethyl-1,2,4-oxadiazole (Coste et al., 2004 ▸). In six of the nine structures (CSD refcodes VOGCOL01, VOGDAY, HAJYUN, HAJYUN01, HAJYUN02 and HAJYUN03; Salorinne et al., 2014 ▸; Coste et al., 2004 ▸), the isoxazole and phenyloxadiazole heterocyclic rings of the WIN framework are almost coplanar, similar to the title compound. However, in two of the structures (CSD refcodes VOGCOL and VOGDEL; Salorinne et al., 2014 ▸), the heterocyclic ring systems are tilted slightly with angles of 34–38° between the ring planes, whereas in one of the structures (CSD refcode VOGCOL; Salorinne et al., 2014 ▸), the heterocyclic ring systems are closer to a perpendicular orientation, with an angle of ca 60.8°. In all of the structures, the propyloxy unit is in a gauche conformation, with torsion angles in the range 62.4–69.2°.
Synthesis and crystallization
An amide coupling reaction of 5-{3-[2,6-dimethyl-4-(5-methyl-1,2,4-oxadiazol-3-yl)phenoxy]propyl}isoxazole-3-carboxylic acid (0.17 mmol, Salorinne et al., 2014 ▸) with 11-amino-1-undecanol (0.18 mmol) in dichloromethane (20 ml) in the presence of N-[3-(dimethylamino)propyl]-N-ethylcarbodiimide (0.19 mmol) and a catalytic amount of 1-hydroxybenzotriazole at 273 K gave the title compound in 68% yield after subsequent chromatographic purification in silica with a dichloromethane–methanol mixture (95:5 v/v). Needle-like crystals of the title compound were obtained from an ethanol solution by vapor diffusion with water.
Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.95–0.99 Å, and with U iso(H) = 1.5U eq(C) for methyl and 1.2U eq(C) for other H atoms, and N—H = 0.88 Å and U iso(H) = 1.2U eq(N). The positions of the O-bound H atoms were located in a difference Fourier map and refined as riding atoms with U iso(H) = 1.5U eq(O). The O—H distance of the half-occupied water molecule was restrained to 0.84 (1) Å.
