실험 절차

A solution of triethylamine (2.0 mL, 15 mmol, 1.8 equiv), 1-hydroxyl benzotriazole monohydrate (2.3 g, 15 mmol, 1.8 equiv), (2R)-4-{4′-[(di-tert-butoxyphosphoryl)oxy]biphenyl-4-yl}-2-methyl-2-(methylsulfonyl)butanoic acid (4.4 g, 8.2 mmol, 1.0 equiv), O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (1.4 g, 12 mmol, 1.4 equiv), and N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDCI) (2.2 g, 11 mmol, 1.4 equiv) in dichloromethane (205 mL) was allowed to stir at room temperature for 1 day. The reaction was diluted with water (600 mL) and dichloromethane (600 mL), the aqueous phase was separated and extracted with dichloromethane (2×300 mL). The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel (60% ethyl acetate in heptane) to provide the title compound (3.29 g, 63%). MS (LCMS) m/z 638.8 (M−1).
