Procedure

A solution of 2,6-dichloro-3-cyano-5-fluoropyridine (134 mg, 0.701 mmol), 2-amino-4,4,4-trifluorobutanamide hydrochloride (135 mg, 0.701 mmol) and DIEA (0.365 mL, 2.10 mmol) in DMSO (3 mL) was stirred at 95 C for 3 h. Water and EtOAc were added. The organic phase was separated, dried over Na2SO4, concentrated in vacuo to give crude 2-(6-chloro-5-cyano-3-fluoropyridin-2-ylamino)-4,4,4-trifluorobutanamide (218 mg).
