Reaction Steps
To a solution of 2-bromo-5-hydroxypyridine (1.04 g, 6 mmol) in 25 mL anhydrous THF was added 2-naphthylboronic acid (1.03 g, 6 mmol) and 2 M aq. sodium carbonate (9 mL, 18 mmol). To this reaction mixture was added palladium tetrakistriphenylphosphine (0.7 g, 0.6 mmol) and the mixture was stirred at rt for 15 h under nitrogen. The reaction mixture was diluted with EtOAc, the organic layer was washed with water (50 mL), brine (50 mL) and dried over anhydrous Na2SO4. Removal of solvent gave a white powder which was purified by column chromatography (Silica Gel 230-400 mesh; 3% MeOH in DCM) to give 6-naphthalen-2-yl-pyridin-3-ol (0.225 g, 17%). MS (ES) m/z: 222.96 (M+1), 221.93 (M); Mp. 168-169° C.
