反応手順

To solution of (2,4,5-trichloro-phenoxyacetic acid (100 mg, 0.39 mmol), 2-amino isonicotinamide (107 mg, 0.78 mmol) and DMAP (96.22 mg, 0.78 mmol) in DMF 12 ml was added PyBOP (409.7 mg, 0.78 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-(2,4,5-trichloro-phenoxy)-acetylamino]-isonicotinamide as a colorless solid (0.06 g, 41% yield).
