tert-Butyl N-[3-hy­droxy-1-phenyl-4-(pyrimidin-2-ylsulfan­yl)butan-2-yl]carbamate monohydrate

In the title hydrate, C(19)H(25)N(3)O(3)S·H(2)O, 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 C(5)S 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.
