In the title compound, C23H22ClN3O, the benzene ring of the 4-chorobenzyl group makes a dihedral angle of 78.56 (6)° with the best plane of the indole ring. The double bond connecting the aza­bicyclic and indole groups adopts a Z geometry. The geometry adopted by the C=N bond with respect to the N—OH bond is trans. The absolute configuration of the compound was determined from refinement of the Flack parameter
