Reaction Steps
To a solution of 5-bromo-N-(2,4-dimethoxybenzyl)-2,4-difluoro-N-(5-fluoropyridin-2-yl)benzenesulfonamide (Preparation 12, 425 mg, 0.90 mmol) in DMSO (5 mL) was added K2CO3 (372 g, 2.70 mmol) followed by 2-fluoro-4-hydroxybenzonitrile (123 g, 0.90 mmol). The reaction mixture was left to stir at room temperature for 18 hours. To the reaction mixture was added water (20 mL) and saturated brine (20 mL) and the product was extracted with EtOAc (50 mL). The organic layer was retained and washed with saturated brine (3×40 mL), dried over MgSO4, and the solvent removed under vacuum. The residue was purified using silica gel column chromatography eluting with 15% EtOAc in heptanes followed by trituration with heptane to afford the title compound as a colourless solid (74 mg, 28%).
