実験手順

A mixture of 4-(4-benzyl-morpholin-2-yl)-2-chloro-phenol (0.50 g; 1.56 mmol), 2,6-dichlorobenzyl bromide (0.39 g; 1.64 mmol) and Cs2CO3 (2.55 g; 7.82 mmol) in CH3CN (20 mL) was heated under reflux overnight. 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)
