실험 절차

To 4-(tert-butyl)-N-{[4-(tert-butyl)phenyl]sulfonyl}-N-[1-methyl-4-(4-methylphenyl)-3-(2-phenoxyethoxy)-1H-pyrazol-5-yl]benzenesulfonamide (Preparation 1) (80 mg) in ethanol (20 ml) at room temperature was added sodium hydroxide (2N, 2 ml) and the mixture was stirred for 16 hrs. The mixture was reduced in volume to 10 ml under reduced pressure, diluted with water (50 ml) and extracted with ethyl acetate (30 ml). The organic fraction was dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica (10 g) eluted with dichloromethane:ether (7:1) to yield the title compound as a colourless glass-like solid (7 mg).
