Procedure

A reaction vessel was charged with 5.25 g (21.2 mmol) of 3-(4-(trifluoromethyl)benzamido)propan-1-ol, 5.72 g (21.2 mmol) of 4-benzyloxy-2,6-dichlorophenol, 5.29 g (20.2 mmol) of triphenylphosphine and 100 ml of tetrahydrofuran, and a solution of 4.08 g (20.2 mmol) of diisopropyl azodicarboxylate dissolved in 20 ml of tetrahydrofuran was added dropwise, while stirring. After stirring at room temperature for 12 hours, the reaction mixture was concentrated, and the residue was subjected to silica gel chromatography, which afforded 1-benzyloxy-3,5-dichloro-4-(3-(4-trifluoromethylbenzamido)propyloxy)benzene.
