Versuchsvorschrift

To solution of 2-[2-(2,4-dichloro-phenoxy)-acetylamino]-isonicotinic acid (16 mg, 0.047 mmol), furfuryl amine (9.1 mg, 0.094 mmol) and DMAP (8.6 mg, 0.07 mmol) in DMF 4 ml was added PyBOP (36 mg, 0.07 mmol) at room temperature, and stirred. 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 resultant crude product was purified by PLC (MeOH:MC=1:9) to afford 2-[2-(2,4-dichloro-phenoxy)-acetylamino]-N-furan-2-ylmethyl-isonicotinamide as a colorless solid (5 mg, 25.3% yield).
