Procedure

To a solution of ethyl [3-[[4-[2-[(tert-butoxycarbonyl)[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]-amino]ethyl]phenoxy]methyl]phenoxy]acetate (1.0 g) in tetrahydrofuran (5.0 ml) was added 4N hydrochloride in dioxane (4.3 ml). The mixture was stirred at room temperature for 8 hours and evaporated under reduced pressure. The residue was diluted with ethyl acetate and saturated sodium bicarbonate solution. The organic layer was separated, washed with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (methanol/chloroform=1/20) to give ethyl [3-[[4-[2-[[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenoxy]-methyl]phenoxy]acetate (632 mg).
