In the title 1,2,4-oxadiazole derivative, C(19)H(18)ClN(3)O(3), the 1,2,4-oxadiazole ring makes dihedral angles of 12.83 (8) and 4.89 (8)°, respectively, with the benzyl and 4-chloro-phenyl rings, while the dihedral angle between the benzyl and 4-chloro-phenyl rings is 11.53 (7)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into helical chains along the b axis. A weak C-H⋯π inter-action is also present.
