실험 절차
Methylmagnesium bromide (3 M in diethyl ether) (28 μL, 0.09 mmol) was added to a 0° C. solution of 4-(2,2-dimethylbutyl)-2-[1-hydroxy-2-oxo-2-(4-pyridin-2-ylphenyl)ethyl]-N,N-dimethyl-1H-imidazole-1-sulfonamide (20 mg, 0.04 mmol) in tetrahydrofuran (2 mL). After stirring at 0° C. until no further reaction (LCMS), the reaction mixture was quenched with saturated aqueous ammonium chloride and extracted with methylene chloride. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 0-100% ethyl acetate/hexane afforded 2-[1,2-dihydroxy-2-(4-pyridin-2-ylphenyl)propyl]-4-(2,2-dimethylbutyl)-N,N-dimethyl-1H-imidazole-1-sulfonamide.
