Reaction Steps
6-Hydroxynaphtoic acid (10.0 g, 53.1 mmol), 2,4-dichloropyridine (9.44 g, 63.8 mmol) and cesium carbonate (51.9 g, 159 mmol) were combined in DMSO (266 mL) and the reaction mixture was heated at 90° C. for 16 h. After cooling to RT, water was added and the aqueous layer was acidified to pH=4-5. The title compound was isolated by filtration and dried under vacuum.
