Procedure
To solution of (4-nitro-phenoxy)-acetic acid (50 mg, 0.25 mmol), 2-amino isonicotinamide (52 mg, 0.37 mmol) and DMAP (62 mg, 0.5 mmol) in DMF 6 ml was added PyBOP (684 mg, 1.31 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:n-Hexane:MeOH=1:2:1˜1:2:2) to afford 2-[2-(4-nitro-phenoxy)-acetylamino]-isonicotinamide as a colorless solid (0.04 g, 50% yield).
