A solution of 2-bromo-4-fluorobenzonitrile (120 mg, 0.600 mmol), (R)-2-amino-3-(thiophen-2-yl)propanamide (93 mg, 0.547 mmol) and DIEA (0.200 mL, 1.15 mmol) in DMSO (3 mL) was stirred at 120 C for 4 d. 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 0-80% EtOAc in hexane to give (R)-2-(3-bromo-4-cyanophenylamino)-3-(thiophen-2-yl)propanamide (35 mg).
