Abstract
In the title compound, C13H16ClFN2O, the piperazine ring is flanked by 1-(2-fluorobenzyl)piperazine and adopts a chair conformation. The dihedral angle between the fluorophenyl ring and the four planar C atoms (r.m.s. = 0.0055 Å) of the piperazine chair is 78.27 (7)°, whereas the dihedral angle between the four planar C atoms of the piperazine chair and the ethanone plane is 55.21 (9) Å; the Cl atom displaced by1.589 (2) Å out of the plane.
