Procedure
To a suspension of (2S)-3-(4-aminophenyl)-2-[[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]-1-propanol dihydrochloride (3.68 g) in a mixed solvent of chloroform and methanol (9:1, 75 ml) was added a saturated aqueous sodium bicarbonate solution (75 ml) and the whole was stirred vigorously. The organic layer was separated and the aqueous layer was extracted with a mixed solvent of chloroform and methanol (9:1, 25 ml×5). The organic layers were combined, dried over magnesium sulfate, filtered, and evaporated to give (2S)-3-(4-aminophenyl)-2-[[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]-1-propanol (2.78 g) as a pale orange crystalline solid.
