Reaction Steps
To (4-iodo-phenoxy)acetic acid (83.5 mg, 0.3 mmol), 3-amino-benzamide (61.3 mg, 0.45 mmol), N-(3-dimethylaminopropyl)-N′-ethyl carbodiimide HCl (EDC) (86.3 mg, 0.45 mmol) and 1-hydroxybenzotriazole (HOBt) (61.3 mg, 0.45 mmol) in DMF (3 ml) was added N,N-diisopropylethylamine, redistilled (DIPEA) (0.08 ml, 0.45 mmol). The mire was stirred overnight, and then partitioned between ethyl acetate and water. The organic phase was washed with brine, dried (MgSO4 anh), and concentrated. The residue was purified by silica gel flash column chromatography (CH2CH2:MeOH=6:1) to give 3-[2-(4-iodo-phenoxy)acetyl-amino]-benzamide as a white solid (105.1 mg, 88.4% yield).
