Procedure

To a slurry of sodium hydride (54 mg, 1.4 mmol, 60% in mineral oil) in DMF (1 mL) was added 4-bromo-2-(1-methyl-1H-pyrazol-5-yl)phenol (Preparation 89, 210 mg, 0.83 mmol) as a solution in DMF (3 mL). After stirring for 30 minutes, 3-cyano-N-(2,4-dimethoxy-benzyl)-4-fluoro-N-thiazol-2-yl-benzenesulfonamide (Preparation 90, 415 mg, 0.957 mmol) was added. After 3 hours the reaction mixture was diluted with ethyl acetate (10 mL) and washed with water (5 mL) and brine (5 mL). The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. Purification by automated flash column chromatography using a 0-100% ethyl acetate/dichloromethane gradient provided the title compound (482 mg, 87%) as a yellow foam.
