Ethyl Acetate → (R)-2-(3-bromo-4-cyanophenylamino)propanamide

Participants

Reaction Steps

A solution of 2-bromo-4-fluorobenzonitrile (200 mg, 1.00 mmol), D-alanine amide hydrochloride (148 mg, 1.19 mmol) and DMA (0.620 mL, 3.56 mmol) in DMSO (3 mL) was stirred at 100 C for 18 h. EtOAc and water were added. The organic phase was separated, dried over Na2SO4, concentrated in vacuo. The residue was purified by a silica gel column, eluted first with 30% EtOAc in hexane, then with 100% EtOAc to give (R)-2-(3-bromo-4-cyanophenylamino)propanamide (185 mg).
