Reaction Conditions

Reaction Steps

A solution of Z-L-leucine-L-leucine-L-norvaline N,O-dimethylhydroxylamide (1.09 g) was dissolved in 20 mL dry tetrahydrofuran (THF) and cooled to 0° C. Lithium aluminum hydride (1 M solution in THF, 3.05 mL) was added and the mixture was stirred at 0° C. for 25 minutes. Potassium bisulfate (465 mg) in 20 mL water was added and the mixture was extracted with EtOAc (3×80 mL). The combined organic layers were washed with aqueous 5% HCl, saturated NaHCO3, and brine, then dried over anhydrous MgSO4, filtered, and evaporated to afford the product (430 mg) as a white solid.
