실험 절차

To a solution of 4-[4-(benzyloxy)-2-oxopyridin-1(2H)-yl]-2-methyl-2-(methylsulfonyl)butanoic acid (670 mg, 1.77 mmol) in methylene chloride (18 mL) at ambient temperature was added 1, (3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (474 mg, 2.47 mmol), 1-hydroxy benzotriazole monohydrate (487 mg, 3.18 mmol), triethylamine (443 uL, 3.18 mmol) and O-tetrahydro-2H-pyran-2-yl-hydroxylamine (310 mg, 2.65 mmol). The resulting mixture was stirred at ambient temperature overnight. The mixture was diluted with methylene chloride and water. The phases were separated and the aqueous layer was extracted with methylene chloride two times. The organic extracts were combined and dried over magnesium sulfate, filtered and concentrated to a crude residue. The crude residue was purified via silica gel chromatography eluting with methylene chloride and methanol. The fractions containing desired product were combined and concentrated to afford 4-[4-(benzyloxy)-2-oxopyridin-1(2H)-yl]-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide as an oil. 536.3 mg LCMS: (M−1) 477.3
