실험 절차

Sodium hydride (16 mg, 60% suspension in mineral oil) was added to a stirred solution of 4-(tert-butyl)-N-[1-(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)-3-(2-hydroxyethoxy)-4-(4-methylphenyl)-1H-pyrazol-5-yl]benzenesulfonamide (105 mg) (Preparation 28) in anhydrous THF (5 ml) at room temperature under a nitrogen atmosphere and the resulting mixture was stirred for 10 minutes at room temperature. DMF (2 ml) was added to the reaction mixture, followed by 5-chloro-2-(methylsulphonyl) pyrimidine (39 mg) and the resulting mixture was stirred at room temperature overnight. The reaction mixture was poured into an aqueous solution of 1.0M citric acid (50 ml) and ether (50 ml) and the aqueous phase was separated. The organic phase was washed with water (30 ml) and then dried over magnesium sulfate, filtered and concentrated under reduced pressure.
