Procedure

Under nitrogen at 5° C., to a solution of tert-butyl [(2R)-2-(3-chlorophenyl)-2-hydroxyethyl][2-(4-hydroxyphenyl)ethyl]carbamate (1.5 g), ethyl [3-(hydroxymethyl)phenoxy]acetate (885 mg) and triphenyl phosphine (1.1 g) in tetrahydrofuran (30 ml) was added diethyl azodicarboxylate (0.66 ml). The mixture was stirred at room temperature for 12 hours and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=2/1) to give ethyl [3-[[4-[2-[(tert-butoxycarbonyl)[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenoxy]methyl]-phenoxy]acetate (1.04 g).
