実験手順

To a solution of 2-Methyl-2-(methylsulfonyl)-4-[4-(1H-pyrazol-1-yl)phenyl]butanoic acid (286 mg, 0.887 mmol) in methylene chloride (8.87 mL) at ambient temperature was added 1,(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (240 mg, 1.2 mmol), 1-hydroxy benzotriazole monohydrate (240 mg, 1.6 mmol), triethyl amine (220 uL, 1.6 mmol) and O-tetrahydro-2H-pyran-2-yl-hydroxylamine (150 mg, 1.3 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 in vacuo 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 in vacuo to afford 2-methyl-2-(methylsulfonyl)-4-[4-(1H-pyrazol-1-yl)phenyl]-N-(tetrahydro-2H-pyran-2-yloxy)butanamide as a solid. 302.9 mg. LCMS: (M−1) 420.3.
