Reaction Steps

Sodium carbonate (0.636 g, 6.0 mmol) in water (2.0 mL) was added to a mixture of 5-bromopyrimidin-2-amine (0.348 g, 2.0 mmol), [3-(tert-butoxycarbonyl)phenyl]boronic acid (0.533 g, 2.4 mmol) and tetrakis(triphenylphosphine)palladium (69 mg, 0.06 mmol) in ethanol (3.0 mL) and toluene (3.0 mL). The resulting mixture was heated at 120° C. for 3 h. The mixture was diluted with EtOAc and washed with water and brine. The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was treated with methanol. The precipitate was filtered and dried to give the product (399 mg, 73.5%). 272.1.
