Reaction Steps
To solution of (4-bromo-2-chloro-phenoxy)-acetic acid (100 mg, 0.37 mmol), 2-amino isonicotinamide (77.89 mg, 0.56 mmol) and DMAP (92.58 mg, 0.75 mmol) in DMF 5 ml was added PyBOP (394.3 mg, 0.75 mmol), and stirred room temperature. Reaction mixture was poured onto ice cold water, diluted by methanol/MC mixture (10%). The organic phase was separated, sequentially washed with aqueous sodium bicarbonate, brine and water, dried over anhydrous MgSO4, and concentrated. The residue was purified by PLC (EtoAC:Hexane:MeOH=3:6:1˜2:4:1) to afford 2-[2-(4-bromo-phenoxy)-acetylamino]-isonicotinamide as a colorless solid (0.076 g, 52% yield).
