Reaction Conditions

Reaction Steps

To a solution of methyl (2R,3R)-2-(3-phenyl-1-propyl)-3-hydroxybutanoate (42.2 g, 179.5 mmol) in THF-methanol (3:1, 535 mL) is added 2 N aqueous sodium hydroxide solution (135 mL, 269.3 mmol). The solution is stirred at 23° C. for 20 h, then concentrated and extracted with hexanes (100 mL). The aqueous layer is acidified to pH 3 with saturated aqueous sodium bisulfate and is extracted with two 500-mL portions of EtOAc. The combined organic layers are dried over magnesium sulfate and concentrated under reduced pressure to provide (2R,3R)-2-(3-phenyl-1-propyl)-3-hydroxybutanoic acid as an oil (33.0 g, 83% yield).
