실험 절차

4′-Hydroxy-3′-(3-nitro-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-4-yl)biphenyl-3-carbonitrile (Preparation 64, 250 mg, 0.64 mmol) was dissolved in DMSO (3.5 mL) and potassium carbonate (177 mg, 1.28 mmol) was added followed by 5-chloro-N-(2,4-dimethoxybenzyl)-2,4-difluoro-N-(1,3,4-thiadiazol-2-yl)benzenesulfonamide (Preparation 16, 310 mg, 0.67 mmol). The reaction was stirred at room temperature for 1 hour and then partitioned between ethyl acetate and water. The aqueous phase was separated and extracted with EtOAc (3×5 mL) and the combined organic layers were washed with brine, dried over anhydrous MgSO4, filtered and concentrated in vacuo. The residue was purified on silica gel by Biotage™ (10% to 80% EtOAc in heptane over 12 CV) to give the title compound (451 mg, 85%) as a light yellow foam.
