In the title hydrate, C19H25N3O3S·H2O, the configuration at each chiral centre in the organic molecule is S, with the hydroxy and carbamate substituents being anti [O—C—C—N torsion angle = −179.3 (3)°]. The thiopyrimidyl and carbamate residues lie to one side of the pseudo-mirror plane defined by the C5S backbone of the molecule; this plane approximately bisects the benzene ring at the 1- and 4-C atoms. The dihedral angle formed between the terminal rings is 5.06 (18)°. In the crystal, supramolecular tubes aligned along the b axis are found: these are sustained by a combination of O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds.

A solution of (2S,3S)-boc-phenylalanine epoxide (1.6 mmol) (Cunico et al., 2009a), mercaptopyrimidine (1.5 mmol) and triethylamine (1.6 mmol) in methanol (10 ml) was stirred at room temperature for 2 h, rotary evaporated and HCl (5%) added to the residue. The mixture was extracted with CH2Cl2 and the combined organic extracts were washed with brine, dried over anhydrous Na2SO4 and evaporated, giving the title molecule in 95% yield. The crude product was purified by crystallization in methanol/water (7:3) to yield colourless needles of (I); M.pt.: 371–373 K..

IR (cm-1; KBr): νmax: 3358 (OH); 3030 (NH); 1686 (C═O); 640 (C—S). The crystals used in the were grown from moist EtOH solution explaining the presence of water in the title structure, (I).
The C-bound H atoms were geometrically placed (C–H = 0.95–1.00 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The O– and N-bound H atoms were located from a difference map and refined with the distance restraints O–H = 0.84 ± 0.01 and N–H = 0.86±0.01 Å, and with Uiso(H) = zUeq(carrier atom); z = 1.5 for O and z = 1.2 for N.

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. |

Compounds having a hydroxyethylamine core play important roles in the medicinal chemistry field. They inhibit aspartyl protease enzymes and are widely used as anti-HIV agents (Brik & Wong, 2003; Ghosh et al., 2001), as inhibitors of BACE-1 to combat Alzheimer's disease (Marcin, et al., 2011) and have also been considered in the treatment of leishmania/HIV-1 co-infections (Trudel et al., 2008). Cunico and co-workers have reported on the in vitro activity of hydroxyethylamine derivatives as anti-malarial agents (Cunico et al., 2009a, 2009b, 2009c, 2011) and in this article we report the structure of the title molecule, isolated from ethanol solution as a monohydrate, (I).
The structure analysis of (I) confirms the stereochemistry at each of the C1 and C7 atoms to be S, Fig. 1, as anticipated from the synthesis. The O1 and N3 substituents on C1 and C7, respectively, have an anti disposition [the O1—C1—C7—N3 torsion angle = -179.3 (3) °]. With reference to the C5S backbone of the molecule, i.e. comprising the C1/C2/C7/C13/C14/S1 atoms, the benzene ring occupies a position that is approximately bisected by the pseudo mirror plane through these atoms [the C7—C13—C14···C17 torsion angle = -17.1 (5) °] whereas the thiopyrimidyl group lies to one side of the plane [the C3—S1—C2—C1 torsion angle = 89.9 (2) °]. The terminal rings of the C5S backbone are almost parallel forming a dihedral angle of 5.06 (18) °. The carbamate residue lies to the same side of the C5S plane as does the thiopyrimidyl group with the t-BuO atoms being directed away from the rest of the molecule.
In the crystal, the water molecules serve to link translationally related hydroxy groups by forming both donor and acceptor interactions, and at the same time the water molecule forms a donor interaction to one of the pyrimidyl-N atoms, Table 1. The resultant supramolecular assembly, a tube, is further stabilized by amine-H···O(carbonyl) interactions. Side-on and end-on views of the supramolecular tube are shown in Figs 2 and 3, respectively. The tubes are aligned along the b direction as seen in Fig. 4.
