Procedure
Methylmagnesium bromide (3 M in diethyl ether) (ca. 15 μL, 0.04 mmol) was added to a 0° C. solution of 4-(2,2-dimethylpropyl)-2-{fluoro[4-(5-fluoropyridin-2-yl)phenyl]acetyl}-N,N-dimethyl-1H-imidazole-1-sulfonamide (10 mg, 0.02 mmol) in tetrahydrofuran (3 mL). After warming slowly to ambient temperature, the reaction was quenched with a few drops of water and concentrated in vacuo. Chromatography over silica eluting with 0-50% ethyl acetate/hexane afforded 4-(2,2-dimethylpropyl)-2-{2-fluoro-2-[4-(5-fluoropyridin-2-yl)phenyl]-1-hydroxy-1-methylethyl}-N,N-dimethyl-1H-imidazole-1-sulfonamide.
