실험 절차

A RBF was charged with 3-chloro-2-cyanopyridine (40 g, 289 mmol), 4-bromophenol (49.9 g, 289 mmol) and cesium carbonate (113 g, 346 mmol). The reactants were suspended in 50 mL of DMSO and allowed to stir at 85° C. overnight. The reaction was cooled to RT and 600 mL of water was added to it. The reaction was filtered and the solid washed with water, then air dried to provide 3-(4-bromophenoxy)-picolinonitrile as a tan solid.
