Procedure

Hydrogen chloride (4 M in 1,4-dioxane) (2 mL, 8 mmol) was added to an ambient temperature solution of 4-(2,2-dimethylbutyl)-2-{1-hydroxy-1-methyl-2-[4-(6-methylpyridin-2-yl)phenyl]ethyl}-N,N-dimethyl-1H-imidazole-1-sulfonamide (120 mg, 0.25 mmol) in methanol (4 mL). After stirring at 70° C. for 1 h, volatiles were removed. The residue was partitioned between methanol/ethyl acetate and 10% aqueous sodium hydroxide. The aqueous phase was extracted with ethyl acetate. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 0-100% acetone/methylene chloride afforded the title compound. (M+H) found: 378.
