実験手順

To N-[3-{2-[(5-bromo-2-pyrimidinyl)oxy]ethoxy}-1-methyl-4-(4-methylphenyl)-1H-pyrazol-5-yl)]4-(tert-butyl)benzenesulfonamide (Example 3) (277 mg) in 1,4-dioxane (7.5 ml) at room temperature was added 2-(tributylstannyl)furan (329 mg) and bis(triphenylphosphine)palladium (II) chloride (32 mg) the mixture was stirred and heated to reflux for 16 hrs. The reaction was diluted with ethyl acetate (100 ml) and washed with a 10% solution of potassium fluoride in water (100 ml), the aqueous portion was then extracted with ethyl acetate (100 ml). The organic fractions were separated and combined, washed with brine (100 ml), dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica (10 g) eluted with ethyl acetate:hexane (3:2) to yield an oil which was dissolved in acetonitrile (20 ml) and washed with hexane (6×10 ml). Evaporation of the acetonitrile under reduced pressure yielded the title compound as a white solid (235 mg).
