Versuchsvorschrift

To a solution of N-[4-(1,3-benzodioxol-5-yl)-3-(2-hydroxyethoxy)-1-methyl-1H-pyrazol-5-yl]-5-isopropyl-2-pyridinesulfonamide (Example 43) (124 mg) in anhydrous THF (5 ml) at 0° C. and under an atmosphere of nitrogen was added sodium hydride (60% dispersion in oil, 33.9 mg) and the mixture was stirred for 5 minutes. To the mixture was added 2-chloro-5-(methylsulfonyl)pyrimidine (93 mg) in dimethylacetamide (1 ml). After being left to stir overnight, the reaction mixture was partitioned between ethyl acetate (100 ml) and saturated ammonium chloride solution (100 ml). The ethyl acetate layer was washed with brine (100 ml), dried over magnesium sulfate, filtered and concentrated to dryness. Purification of the residue on a Phenomenex Magellen™ column eluting in an isocratic fashion with acetonitrile:ammonium acetate solution (0.1M) (3:7) afforded the title compound as a white solid (11 mg).
