title: N-(4-Chloro-phen-yl)-4-(2-oxocyclo-pent-yl)butyramide.
abstract: In the title compound, C(15)H(18)ClNO(2), the amide group is coplanar with the chloro-phenyl group, making a dihedral angle of 1.71 (12)°. The cyclo-penta-none ring adopts a twist conformation. A weak intra-molecular C-H⋯O hydrogen bond is observed. Mol-ecules are linked into cyclic centrosymmetric dimers by paired N-H⋯O hydrogen bonds.
