The title compound, C14H15F3N2O4S·C2H5OH, was prepared by reaction of 4-hydroxybenzaldehyde, ethyl 4,4,4-trifluoro-3-oxobutanoate and thiourea. The hexahydropyrimidine ring adopts a half-chair conformation, the mean plane formed by the ring atoms excluding the C atom bonded to the ethoxycarbonyl group has an r.m.s. deviation of 0.0333 Å, and the dihedral angle between this plane and the benzene ring is 56.76 (5)°. The molecular conformation is stabilized by an intramolecular O—H⋯O hydrogen bond, generating an S(6) ring. The is stabilized by intermolecular O—H⋯O, O—H⋯S, N—H⋯O and N—H⋯S hydrogen bonds. The ethyl group of the ester unit is disordered over two positions, with an occupancy ratio of 0.757 (10):0.243 (10).

The title compound was synthesized by refluxing for 3 h a stirred solution of 4-hydroxybenzaldehyde (2.45 g, 20 mmol), ethyl 4,4,4-trifluoro-3-oxobutanoate (4.42 g, 24 mmol) and thiourea (2.28 g, 30 mmol) in 20 ml of anhydrous ethanol. The reaction was catalyzed by sulfamic acid (0.6 g). The solvent was evaporated in vacuo and the residue was washed with water. The title compound was recrystallized by slow evaporation of a 50% aqueous ethanol solution.
H atoms involved in hydrogen-bonding inetractions were located by difference Fourier methods and their positional and isotropic displacement parameters were refined. Other H atoms were placed in calculated positions, with C—H(aromatic) = 0.95 Å and C—H(aliphatic) = 0.98 Å or 0.99 Å, and treated as riding, with Uiso(H) = 1.2Ueq(C).

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. |

Dihydropyrimidine (DHPM) derivatives can be used as potential calcium channel blockers (Zorkun et al., 2006), inhibitors of mitotic kinesin Eg5 for treating cancer (Cochran et al., 2005; Brier et al., 2004) and as TRPA1 modulators for treating pain (Moran et al., 2007). In addition, compounds that contain fluorine have special bioactivity, e.g. flumioxazin is a widely used herbicide (Hermann et al., 2003; Ulrich, 2004). This led us to focus our attention on the synthesis and bioactivity of these important fused perfluoroalkylated heterocyclic compounds. During the synthesis of DHPM derivatives, the title compound, an intermediate C14H15F3N2O4S.C2H5OH was isolated and the structure confirmed by X-ray diffraction.
In the structure of the title molecule, the 1,3-diazinane ring adopts a half-chair conformation, the mean plane formed by the ring atoms excluding the C atom bonded to the ethoxy carbonyl group has an r.m.s. deviation of 0.0333 Å, the dihedral angle between the mean plane and benzene ring is 56.76 (5)°. The molecular conformation is stabilized by intramolecular O—H···O hydrogen bond, generating an S(6) ring. The crystal structure is stabilized by intermolecular hydrogen bonds (O—H···O, O—H···S, N—H···O and N—H···S). The ethyl group of the ester unit is disordered over two positions, with a site-occupancy ratio of 0.757 (10):0.243 (10). For a crystal structure related to the title compound, see: Song et al., 2010.
