In the title benzamide derivative, C(11)H(14)ClNO, the chloro-benzene and butyl-amine groups are each planar, with mean deviations from the planes of 0.013 and 0.030 Å, respectively, and a dihedral angle of 2.54 (9)° between the two planes. In the crystal structure, N-H⋯O hydrogen bonds link mol-ecules in rows along a. Short inter-molecular Cl⋯Cl inter-actions [3.4225 (5) Å] link these rows into sheets in the ac plane. Additional weak C-H⋯O and C-H⋯π inter-actions generate a three-dimensional network.
