Procedure

A solution of 2-bromo-4,5-difluorobenzonitrile (123 mg, 0.564 mmol), 2-amino-4,4,4-trifluorobutanamide (88 mg, 0.564 mmol) and DIEA (0.250 mL, 1.43 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. The residue was purified by a silica gel column, which was eluted with 0-70% EtOAc in hexane to give 2-(5-bromo-4-cyano-2-fluorophenylamino)-4,4,4-trifluorobutanamide (90 mg).
