In the title compound, C(26)H(25)ClN(4)O(3)S, the acyclic imine group exhibits an E configuration. The triazole ring is oriented at dihedral angles of 53.84 (2), 70.77 (1) and 32.59 (3)° with respect to the benzene rings of the 2-chloro-benzyl-idene, 4-methyl-benzyl-sulfanyl and 3,4,5-trimethoxy-phenyl groups, respectively. The crystal packing is stabilized by weak inter-molecular C-H⋯N, C-H⋯S and C-H⋯π inter-actions.
