In the title compound, C24H27N5O2S·0.5H2O, the piperidine ring adopts a distorted boat conformation. The phenyl rings subtend dihedral angles of 69.7 (1) and 88.7 (1)° with the best plane through the piperidine moiety. In the crystal, symmetry-related molecules are linked through a network of C-HO and C-HN interactions, the former connecting them into zigzag chains along the c-axis direction and the latter forming an R22(4)motif. The dimer formation (C-HN) and the repetition of symmetry-related molecules (C-HO) along the b-axis direction stabilize the packing mode. The water molecule is located on a twofold rotation axis.
