Reaction Steps

A solution of 2-bromo-4,5-difluorobenzonitrile (150 mg, 0.688 mmol), (R)-2-amino-3-(pyridin-2-yl)propanamide hydrochloride (170 mg, 0.714 mmol) and DIEA (0.500 mL, 2.87 mmol) in DMSO (4 mL) was stirred at 120 C for 18 h. Water and EtOAc were added. The organic phase was separated, dried over Na2SO4, concentrated in vacuo to give (R)-2-(5-bromo-4-cyano-2-fluorophenylamino)-3-(pyridin-2-yl)propanamide (274 mg)
