Procedure
A mixture of 3-bromo-2-chloropyridine (10 g, 52 mmol), 4-chlorophenol (6.7 g, 52 mmol), cesium carbonate (34 g, 104 mmol) in 100 mL DMSO was heated to 90° C. with stirring overnight. The reaction mixture was dilution with DCM and washed with water and brine. The organic layer was dried over Na2SO4 and concentrated. The residue was purified by silica gel chromatography (0-30% EtOAc/hexane) to provide the title compound.
