The title mol-ecule, C(30)H(37)N(5)S, displays a chair-shaped piperazine ring, as well as an approximately planar triazole ring [maximum deviation = 0.002 (2) Å] whose phenyl substituent is nearly perpendicular to the mean plane of the five-membered ring [dihedral angle = 80.4 (1)°]. The substit-uents on the piperazine ring occupy equatorial sites. Weak inter-molecular C-H⋯S hydrogen bonding is present in the crystal structure.
