Procedure

A solution of 2-bromo-4,5-difluorobenzonitrile (218 mg, 1.00 mmol), (R)-2-amino-3-cyclopropylpropanamide (188 mg, 1.14 mmol) and DIEA (0.600 mL, 3.45 mmol) in DMSO (3 mL) was stirred at 120 C for 18 h. Water and EtOAc were added. The organic phase was separated, washed with water, dried over Na2SO4, concentrated in vacuo to give (R)-2-(5-bromo-4-cyano-2-fluorophenylamino)-3-cyclopropylpropanamide (326 mg).
