実験手順
To a solution of diastereopure 3-((R)-1-phenylethylamino)-2-(4-bromophenyl)propyl acetate (2.85 g, 7.57 mmol) in methanol (30.3 ml) was added 1.0N-sodium hydroxide (30.3 ml, 30.3 mmol) at 0° C. The mixture was stirred at room temperature for 3 hours. The mixture was partitioned between saturated ammonium chloride solution and chloroform, and the organic layer was dried over sodium sulfate. The solvent was evaporated under reduced pressure to afford diastereopure 3-((R)-1-phenylethylamino)-2-(4-bromophenyl)propan-1-ol as white solid (2.40 g, 95%).
