Reaction Steps
A mixture of sodium carbonate decahydrate (86.0 g), tetrakis(triphenylphosphine)palladium(0) (7.76 g), (4-((tert-butyldimethylsilyl)oxy)phenyl)boronic acid (40 g) and 3-bromopyridin-2-amine (26.9 g) in DME (500 mL) and water (50 mL) was stirred at 90° C. for 24 hr. After cooling to room temperature, the aqueous layer was removed. The organic layer was filtered with NH-silica gel cartridge, and washed with EtOAc. The filtrate was concentrated in vacuo. The residue was recrystallized from EtOAc-IPE to give the title compound (25.0 g) as a pale yellow solid.
