실험 절차
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (443 mg) in one portion was added to a mixture of N-Boc-L-norvaline dicyclohexylammonium salt (838 mg), N,O-dimethylhydroxylamine hydrochloride (215 mg), 1-hydroxybenzotriazole monohydrate (340 mg), and N-methylmorpholine (0.28 ml) in dimethyl formamide (DMF, 20 ml) at 0° C. The mixture was stirred at 0° C. for 2 hours, then at room temperature for 40 hours. The reaction was quenched with water (80 mL) and the mixture was extracted with ethyl acetate (EtOAc, 3×100 mL). The combined organic layers were washed with aqueous 10% hydrogen chloride (HCl), saturated sodium bicarbonate (NaHCO3), and brine, then dried over anhydrous magnesium sulfate (MgSO4), filtered, and evaporated to afford the product (546 mg) as an oil.
