Versuchsvorschrift

To 4-(tert-butyl)-N-{[4-(tert-butyl)phenyl]sulfonyl}-N-[3-[2-(4-fluorophenoxy)ethoxy]-1-methyl-4-(4-methylphenyl)-1H-pyrazol-5-yl]benzenesulfonamide (Preparation 25) (180 mg) in dioxan (5 ml) at room temperature was added 1N aqueous sodium hydroxide (5 ml) and the mixture was stirred and heated to 100° C. for 1.5 hrs. The reaction was partitioned between 2N aqueous hydrochloric acid (25 ml) and ethyl acetate (25 ml). The organic layer was separated, washed with water, then brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography using silica gel (20 g), eluting with a solvent gradient of pentane:ethylacetate (19:1 changing to 7:3), to yield the title compound as a glass (106 mg).
