After cooling to RT the resulting mixture was partitioned between EtOAc and water. The layers were separated and the organic layer, dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by column chromatography (SiO2, CH2Cl2:MeOH 98:2) to afford 4-benzyl-2-[3-chloro-4-(2,6-dichloro-benzyloxy)-phenyl]-morpholine (0.74 g)
