Versuchsvorschrift

To solution of (2,4-dichloro-phenoxy)-acetic acid (51 mg, 0.23 mmol), 2-amino isonicotinamide (47.66 mg, 0.34 mmol) and DMAP (56.6 mg, 0.46 mmol) in DMF 4 ml was added PyBOP (236 mg, 0.46 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-dichloro-phenoxy)-acetylamino]-isonicotinamide as a colorless solid (0.06 g, 77% yield).
