Procedure

Hydrogen chloride (4 M in 1,4-dioxane) (1 mL, 4 mmol) was added to a solution of 4-(2,2-dimethylbutyl)-2-{1-hydroxy-1-methyl-2-[4-(1H-pyrazol-4-yl)phenyl]ethyl}-N,N-dimethyl-1H-imidazole-1-sulfonamide (100 mg, 0.22 mmol) in methanol (1 mL). After stirring at 70° C. for 1 h, volatiles were removed in vacuo. 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 to afford the title compound. (M+H) found: 353.
