Reaction Steps

To a solution of 6-hydroxy-1-napthoic acid (2 g, 10.6 mmol) in DMSO (5 mL), Cs2CO3 (14 g, 42.4 mmol) was added and stirred at RT 10 min. 4-Chloropyridine hydrochloride (1.9 g, 12.7 mmol) was added in one portion and the reaction mixture heated to 140° C. for 12 h. The reaction mixture was cooled to RT, diluted with water and made pH 5 using 6 N HCl, at which point a brown precipitate crashed out. The solid was filtered and rinsed with water and hexanes to yield the title compound.
