Reaction Conditions

Reaction Steps

To a solution of (3R,4S)-1-(2-tetrahydropyranyloxy)-3-(3-(4-chlorophenyl)-1-propyl)-4-methylazetidin-2-one (360 mg, 1.07 mmol) in dioxane (3.2 mL) is added 1 M aqueous sodium hydroxide (1.6 mL). The solution is stirred at 23° C. for 72 h, then extracted with hexanes (20 mL). The aqueous layer is acidified to pH=3 with saturated aqueous sodium bisulfate solution, and is extracted with two 30 mL portions of ethyl acetate. The combined organics are washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to provide (2R,3S)-2-(3-(4-chlorophenyl)-1-propyl)-3-(2-tetrahydropyranyloxyamino)butanoic acid as an oil (380 mg, 99% yield).
