Versuchsvorschrift

Diisopropylethylamine (35 uL, 0.2 mmol, 2.1 equiv) and 1-hydroxyl benzotriazole monohydrate (27 mg, 0.18 mmol, 1.9 equiv) were added sequentially to a solution of 2-ethyl-2-(methylsulfonyl)-4-(2-oxo-4-phenylpyridin-1(2H)-yl)butanoic acid (34 mg, 0.09 mmol, 1.0 equiv) in dichloromethane (2 mL) at room temperature. After 30 min, O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (15 mg, 0.12 mmol, 1.3 equiv) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (26 mg, 0.13 mmol, 1.4 equiv) were added, and the reaction was allowed to stir overnight. Water (2 mL) was added, the organic phase was separated, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The crude material was purified by flash chromatography (1:1-0:1 heptane/ethyl acetate) to provide a colorless oil (45 mg, 100%). MS (LCMS) m/z 461.8 (M−1).
