In the title compound, C10H14Cl2N2O2, the five-membered ring adopts an envelope conformation (with the methylene C atom closest to the C—N bridge as the flap), while the conformation of the six-membered ring is close to a twist-boat. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds, forming chains along the c-axis direction.
