Procedure

A solution of tert-butyl [4-[4-[2-[N-(tert-butoxycarbonyl)-N-[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]-amino]ethyl]benzyl]phenoxy]acetate (240 mg) and 4N hydrochloride in 1,4-dioxane (3.0 ml) was stirred at room temperature for 24 hours. The mixture was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (methanol/acetic acid/chloroform=10/1/100) to give a product. To a tetrahydrofuran (2.0 ml) solution of the product, 4N hydrogen chloride in 1,4-dioxane (1.0 ml) was added. The mixture was stirred for 5 minutes and evaporated under reduced pressure to give [4-[4-[2-[[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]benzyl]phenoxy]acetic acid hydrochloride (72 mg).
