Reaction Steps

To a microwave vial was added 3-amino-5-bromopyridine (LII) (0.400 g, 2.31 mmol), 3-fluorophenyl boronic acid (XLIX) (0.356 g, 2.54 mmol), tetrakis(triphenylphosphine)palladium(0) (0.133 g, 0.116 mmol), potassium phosphate (0.736 g, 3.47 mmol), water (1 mL), and DMF (5 mL). The reaction vial was capped, purged with argon and heated under microwave irradiation for 1 h at 180° C. The solution was filtered through a pad of Celite and concentrated under vacuum. The residue was purified by column chromatography (4:6 EtOAc:hexanes→7:3 EtOAc:hexanes) to afford the 5-(3-fluorophenyl)pyridin-3-amine (LIII) (0.360 g, 1.92 mmol, 83% yield) as a yellow-white solid. ESIMS found for C11H9FN2 m/z 189.1 (M+H).
