Reaction Steps

To a solution of 6-hydroxy-1-naphthoic acid (10.0 g, 53.1 mmol) in DMSO (60 mL) was added Cs2CO3 (51.9 g, 159.4 mmol). Bubbling was evident. The mixture was stirred at RT for 5 min, at which time 2,4-dichloropyrimidine (15.8 g, 16.3 mmol) was added. The reaction was stirred at RT and monitored by LCMS for the disappearance of starting material. EtOAc (1.0 L) was added, and the reaction was filtered to remove solid Cs2CO3. The mixture was extracted with 2N aqueous NaOH. The aqueous layer was washed with EtOAc, then acidified with 6N aqueous HCl to provide a white suspension. Filtration yielded a white solid.
