3-Bromo-2-chloropyridine (10.3 g, 53.4 mmol), 4-aminophenol (7.00 g, 64.1 mmol), cesium carbonate (34.8 g, 107 mmol), and DMSO (53 ml, 53.4 mmol) were added into a pressure tube. The tube was capped and placed in a preheated oil bath at 130° C. After 16 h, the reaction mixture was stirred and cooled in ice-water. Water was added slowly to the mixture and the product precipitated out as a gray solid. The solids were washed with water, dried under vacuum at RT to afford 4-(3-bromopyridin-2-yloxy)benzenamine. MS Calcd for C11H9BrN2O: [M]+=264. Found [M+H]+=265.
