To solution of 3-[2-(2,4-dichloro-phenoxy)-acetylamino]-benzoic acid (100.3 mg, 0.3 mmol), furfuryl amine (58.3 mg, 0.06 ml, 0.6 mmol), 4-dimethylaminopyridine (73.4 mg, 0.6 mmol) and PyBOP (312.3 mg, 1.0-mmol) in DMF 5.0 mL was stirred. Reaction mixture was separated by EtoAC and brine. The organic phase was dried (MgSO4 anh) and concentrated. The residue was purified by silica gel column chromatography (CH2Cl2:MeOH=10:1) to give 3-[2-(2,4-dichloro-phenoxy)-acetylamino]-N-furan-2-ylmethyl-benzamide as a white solid (144.6 mg, 90% yield).
