実験手順

To solution of (4-bromo-phenoxy)-acetic acid (100 mg, 0.43 mmol), 2-amino isonicotinamide (89.39 mg, 0.65 mmol) and DMAP (106 mg, 0.86 mmol) in DMF 5 ml was added PyBOP (452 mg, 0.86 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 (0.083 g, 55% yield).
